-<P>The script tries to keep track of the databases used in different workareas.
-But the flow through your program cannot be determined, so in some cases
-you have to help the script a bit by giving additional info.</P>
-<P>Three special comments have been designed to add this info:</P>
-<PRE>* XB2CPP(SelectedArea)
-or&nbsp; * XB2CPP(SelectedArea,Workarea1,Alias1,Wa2,Al2...)
-or&nbsp; * XB2CPP(SelA,WA1,Al1[Total1, Active1],Wa2, Al2[Tot2,Act2])</PRE>
-<P>e.g. * XB2CPP(3,3,ZP,2,PL) will inform the script for example at the beginning
-of a PROCEDURE that a database with Alias ZP is opened in workarea 3 and
-a database with alias PL is opened in workarea2 and when calling this procedure
-always workarea 3 is selected.</P>
-<P>The third alternative of this statement makes it possible to define
-the number of open indices and which one is the active index, as given
-by a previous SET INDEX TO or USE and SET ORDER TO statements. The script
-cannot know, which procedures, statements have been executed before and
-opened indices.... So * XB2CPP(2,2,ZP[2,1]) will inform the script about
-an open database alias ZP in workarea 2 which is currently selected and
-has two open indices where the first one is the active one.</P>
-<H2>Hints</H2>
-
-<OL>
-<LI>Always give an ALIAS in USE-Statements this is needed for generation
-of the Database Classnames</LI>
-<LI>Give the above described additional infos where necessary.</LI>
-<LI>Use ALIASes in Expressions with database fields, this helps the script
-in knowing where database references are.</LI>
-<LI>Replace the XXX in PutXXXField or GetXXXField manually the script is
-not able to determine variable or field types. The code for getting a Textfield
-(GetField) must also be corrected. Xbase DBMS Syntax requires the buffer
-as second parameter, the string will not be returned ! You may use a C++
-String wrapper for this job.</LI>
-<LI>PROCEDURES that will operate on two different databases where some statements
-are used for both cannot be converted The script needs to know everytime
-on which database the statements are operating. Either duplicate such procedures,
-(one for each database), or write a generic C++ routine with pointers to
-databases.</LI>
-<LI>Don't assume any compilable or even working C++ source code as output.
-The ambigous DBASE language, which lacks type and variable definitions
-is one reason for this. This script only will help you for about 10-30%
-of the conversion. The rest (which remained uppercase) has to be done manually
-:)</LI>

-NOTE! The LGPL below is copyrighted by the Free Software Foundation, but
-the instance of code that it refers to (the XBase libraries) are copyrighted

-
----------------------------------------------------------------------------
- GNU LIBRARY GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1991 Free Software Foundation, Inc.
- 59 Temple Place - Suite 330
- Boston, MA 02111-1307, USA.
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the library GPL. It is
- numbered 2 because it goes with version 2 of the ordinary GPL.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Library General Public License, applies to some
-specially designated Free Software Foundation software, and to any
-other libraries whose authors decide to use it. You can use it for
-your libraries, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if
-you distribute copies of the library, or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link a program with the library, you must provide
-complete object files to the recipients so that they can relink them
-with the library, after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- Our method of protecting your rights has two steps: (1) copyright
-the library, and (2) offer you this license which gives you legal
-permission to copy, distribute and/or modify the library.
-
- Also, for each distributor's protection, we want to make certain
-that everyone understands that there is no warranty for this free
-library. If the library is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original
-version, so that any problems introduced by others will not reflect on
-the original authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that companies distributing free
-software will individually obtain patent licenses, thus in effect
-transforming the program into proprietary software. To prevent this,
-we have made it clear that any patent must be licensed for everyone's
-free use or not licensed at all.
-
- Most GNU software, including some libraries, is covered by the ordinary
-GNU General Public License, which was designed for utility programs. This
-license, the GNU Library General Public License, applies to certain
-designated libraries. This license is quite different from the ordinary
-one; be sure to read it in full, and don't assume that anything in it is
-the same as in the ordinary license.
-
- The reason we have a separate public license for some libraries is that
-they blur the distinction we usually make between modifying or adding to a
-program and simply using it. Linking a program with a library, without
-changing the library, is in some sense simply using the library, and is
-analogous to running a utility program or application program. However, in
-a textual and legal sense, the linked executable is a combined work, a
-derivative of the original library, and the ordinary General Public License
-treats it as such.
-
- Because of this blurred distinction, using the ordinary General
-Public License for libraries did not effectively promote software
-sharing, because most developers did not use the libraries. We
-concluded that weaker conditions might promote sharing better.
-
- However, unrestricted linking of non-free programs would deprive the
-users of those programs of all benefit from the free status of the
-libraries themselves. This Library General Public License is intended to
-permit developers of non-free programs to use free libraries, while
-preserving your freedom as a user of such programs to change the free
-libraries that are incorporated in them. (We have not seen how to achieve
-this as regards changes in header files, but we have achieved it as regards
-changes in the actual functions of the Library.) The hope is that this
-will lead to faster development of free libraries.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, while the latter only
-works together with the library.
-
- Note that it is possible for a library to be covered by the ordinary
-General Public License rather than by this special one.
-
- GNU LIBRARY GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library which
-contains a notice placed by the copyright holder or other authorized
-party saying it may be distributed under the terms of this Library
-General Public License (also called "this License"). Each licensee is
-addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
- You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
- 2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
- a) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works. But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
- If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
- 6. As an exception to the Sections above, you may also compile or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- c) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- d) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the source code distributed need not include anything that is normally
-distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License. However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
- 9. You are not required to accept this License, since you have not
-signed it. However, nothing else grants you permission to modify or
-distribute the Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions. You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
- 11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License. If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices. Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded. In such case, this License incorporates the limitation as if
-written in the body of this License.
-
- 13. The Free Software Foundation may publish revised and/or new
-versions of the Library General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation. If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
- 14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission. For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this. Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
- NO WARRANTY
-
- 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
- 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.

-Beginning with release 3.0 exception processing has been removed from the
-library. There were reports that it was not 100% working, so I trimmed the
-library back to working code. If there are any volunteers to re-install the
-exception processing, AND test it, let me know. Thanks - Gary
-
-It is generally a good idea to check the method return codes to verify an
-error hasn't occured. Most Xbase DBMS methods return a SHORT return code

-<TITLE>Xbase DBMS Chapter 1</TITLE>
-<BODY BGCOLOR=#FFFFFF>
-
-<h1><p align="center">Getting Started</p></h1>
-<p align="center">Chapter Updated 8/14/03</p>
-
-<hr><h2>Overview</h2>
-
-Welcome to Xbase DBMS. Xbase DBMS is a collection of specifications,
-programs, utilities and a C++ class library for manipulating Xbase type
-datafiles and indices. Xbase has been developed and produced by several
-people from around the world via the internet.
-<br><br>
-
-The term Xbase is often used used to describe the format of the original
-DBase, Clipper and Foxbase (.DBF) files. Many vendors support the industry
-standard Xbase file format and are committed to this technology for many
-years to come, thus insuring continued support.<br><br>
-
-The original purpose of the Xbase library was to provide reliable and
-economical programming tools to programmers for reading, writing and updating
-DBF databases, indices and memo fields.<br><br><br>
-
-<hr><h2>System Requirements</h2>
-
-To use Xbase DBMS, the following items are needed:<br><br>
-
-A computer and C/C++ compiler.<br><br>
-
-The original source code is developed on a Linux platform with the GCC
-public domain C/C++ compiler.
-<br><br>
-
-Xbase DBMS has been successfully ported and runs on Linux, Sun Solaris,
-OpenVMS, FreeBSD, OS2 and DOS/Windows (Using the large memory model).
-<br><br>
-
-This software is not intended to be used on any system using an SCO operating
-system.
-<br><br>
-
-<hr><h2>Classes and User Interface</h2>
-
-There are six classes in the Xbase library which are available
-for use in a typical Xbase application program.<br><br><br>
-
-<CENTER><TABLE BORDER>
-<CAPTION ALIGN=TOP><H3>Xbase Classes - Version 1.8.0 and newer</H3></CAPTION>
-<TR VALIGN=BASELINE>
-<TR><TH ALIGN=LEFT>Class<TD>Basic Description<TD>How Used<TD>Old Class<br>Name
-<TR><TH ALIGN=LEFT>xbXBase<TD>Basic Xbase Class<TD>Every program gets one of these<TD>XBASE
-<TR><TH ALIGN=LEFT>xbDbf<TD>Database and Field class<TD>Need one of these for each open DBF file<TD>DBF
-<TR><TH ALIGN=LEFT>xbNdx<TD>Ndx index class<TD>Need one of these for each open NDX index<TD>NDX
-<TR><TH ALIGN=LEFT>xbNtx<TD>Ntx index class<TD>Need one of these for each open NTX index
-<TR><TH ALIGN=LEFT>xbString<TD>String class<TD>Used for handling strings
-<TR><TH ALIGN=LEFT>xbHtml<TD>Html generation class<TD>Needed for creating HTML code<TD>HTML
-</TABLE></CENTER>
-<br><br>
-There are other classes used internally by these Xbase classes, but most
-application programs need not to be concerned with. These classes are
-xbStack - used for stack data structures, xbExpn - used for expression
-logic, and xbDate - used for date manipulation logic.
-
-<br><br>
-<hr><h2>Portability, Type Defs and Structures</h2>
-
-To effectively make the Xbase library as portable across platforms as possible,
-three things occured.
-<br><br>
-<li>First, the software was developed to run and compile on either big endian
-or little endian computers and store all numeric data in little endian format.
-<br><br>
-<li>Secondly, field types must be consistently defined in each environment. The <em>types.h</em>
-file defines the xbase data types. To modify the Xbase code base to function
-in a different (non ported to yet) environment, start by modifying the <em>types.h</em>
-file for your site and recompile.<br><br>
-<li>Thirdly, support for unix automake and autoconf has been to provided
-support on a wide variety of unices.
-<hr><br><br>
-<CENTER>
-<TABLE BORDER>
-<CAPTION ALIGN=TOP><h3>Field Types</h3></CAPTION>
-<TR ALIGN=BASELINE>
-<TR><TH ALIGN=LEFT>Type<TD>Description
-<TR><TH ALIGN=LEFT>xbULong<TD>unsigned long int
-<TR><TH ALIGN=LEFT>xbUShort<TD>unsigned short int
-<TR><TH ALIGN=LEFT>xbShort<TD>short int

-<TR><TH ALIGN=LEFT>void<TD>void
-<TR><TH ALIGN=LEFT>struct SCHEMA<TD>Used for defining record structures
-</TABLE></CENTER>
-<br><br>
-
-Xbase was designed for portability utilizing standard ANSI-C compliant
-code. If you decide to write updates to the Xbase project, please try
-to keep your work to standard generic ANSI-C (no special DOS/WINDOWS Calls).
-<br><br>
-
-<hr><h2>Compilation Overview</h2>
-If you are building the sources on a Linux/Unix platform:<br><br>
-Download the source<br>
-./configure<br>
-make<br>
-su<br>
-make install<br>
-exit<br><br>
-
-<br><br>
-Before compiling the library, you may need to modify the options for your
-environment. Do "./configure --help" for a list of the current options
-
-<br><br>
-On my server, I had to:
-<li>Verify the library and associated links were copied from xbase/xbase/.libs
-into /usr/local/lib
-<li>Add /usr/local/lib is in /etc/ld.so.conf
-<li>execute program <em>ldconfig</em> as root to refresh the new libs
-
-<br><br>
-Actual milage at your site may vary.
-<br><br>
-
-<hr><h2>Building a program with the Xbase library</H2>
-
-Create a directory for your project:<br><br>
-
-cd /home/me<br>
-mkdir MyProject<br>
-cd MyProject<br>
-vi MyProg.cpp<br><br>
-
-To use the Xbase classes, include the following header file in the program:
-<br><br>
-
-#include &lt;xbase/xbase.h&gt;<br><br>
-
-For more details, check out the sample programs in the
-xbase/examples directory.
-<br><br>
-<hr><h2>Compiling and Linking Unix Application Program for v3.0 later</h2>
-
-The install script should have provided specific instructions for your
-environment on how to link with the xbase library. <br><br>
-
-In the Linux environment, assuming that you are using shared libraries,
-and usr/local/lib has been added to
-the /etc/ld.so.conf file, and the ldconfig command was executed
-<br><br>
-
-To Compile:<br>
-g++ -c -Wall -I/usr/include -I/usr/src/linux/include-asm-i386 -I/usr/local/include
--I/usr/local/xbase myprog.cpp<br><br>
-To Link Edit:<br>
-g++ -o myprog myprog.o libxbase.so<br><br>
-
-<hr><h2>Compiling an Application Program with Borland v4.5 C/C++compiler</h2>
-With Borland C compiler: bcc -Ic:\xbase\src myprog.cpp -Lc:\xbase\src\xbase.lib
-<br><br>
-
-<hr><h2>Getting the latest development version of XBase</h2>
-
-<br>The Xbase project is in an ongoing state of development with new
-enhancements being added and bug fixes being applied as they are found
-and the package maintainers have time. There are several programmers
-from various parts of the world working on Xbase. If you would like to
-get the latest version of the Xbase library for your project, it is
-available on sourceforge.net.
-
-<br><h3>Notes about using the current development library</h3>
-<li>1 - Library functions may or may not be documented
-<li>2 - The library may or may not be stable. This is the development library
-and is being updated with current code changes. If you are using it, and it
-does not behave the way you think it should, you may want to drop a note to
-<A HREF="mailto:xdb-devel@lists.sourceforeg.net">xdb-devel@lists.sourceforge.net
-</A> This may sound a little unsettling, but the
-library is generally stable. It goes through periods of time where it is in
-a state of flux when major changes are occurring, but for the most part it is
-probably OK to use.
-<li>3 - If you have changes to contribute to the library, mail your updates
-to<A HREF="mailto:xdb-devel@lists.sourceforge.net">
-xdb-devel@lists.sourceforge.net</A><br>.

-<h3>Method: xbShort xbDbf::CreateDatabase( char *FileName,
- xbSchema *s, xbShort OverLay )</h3><br>
-This method creates an Xbase (.DBF) file with the name
-of FileName and builds the header record with the format as
-defined in the <em>xbSchema</em> parameter. The <em>OverLay</em> switch is
-used to determine what to do if a xbDbf file with the same name
-already exists. If <em>OverLay</em> is set to XB_OVERLAY and the file exists,
-the file is overwritten, otherwise an error is returned.<br><br>
-<em>Overlay Switch</em> is:<br>
-<li>XB_OVERLAY = Overlay file if it exists<br>
-<li>XB_DONTOVERLAY = Return with error if file exists<br><br>
-<em>xbSchema</em> has the following format:<br>
-<xmp>
-xbSchema MyRecordSchema[] =
-{
- { FieldName, Type, FieldLength, NoOfDecimals },
- { FieldName2, Type, FieldLength, NoOfDecimals },
- ...
- { "",0,0,0 }
-};
-</xmp>
-Where:<br>
-<li><em>FieldName</em> is the name of the data field.<br>
-<li><em>Type</em><br><br>
-<h4>Version 1.7.4 and greater:</h4>
-XB_CHAR_FLD or C<br>
-XB_DATE_FLD or D<br>
-XB_LOGICAL_FLD or L<br>
-XB_MEMO_FLD or M<br>
-XB_FLOAT_FLD or F<br>
-XB_NUMERIC_FLD or N<br><br>
-<li><em>FieldLength</em> is the length of the field.<br>
-<li><em>NoOfDecimals</em> is the number of decimals for NUMERIC fields.<br>
-<br>
-The record buffer is automatically set to spaces when this method is called.

-
- Several of the tests pass either StringDate or Chardate to the method
- being tested - this is done to test the class methods. In actual usage,
- this may not be necessary due to the instance of the class already
- containing a date value.

-This chapter lists the xbNdx and xbNtx index methods and provides
-examples of how to use them.<br><br>
-
-There are many methods in the xbNdx and xbNtx classes which are used for
-maintaining and updating NDX and NTX files. Fortunately for the
-application programmer, most of the complexities of dealing with the
-NDX and NTX indices are automatically cared for by the Xbase library.<br><br>
-
-xbNdx and xbNtx methods which are used by application programs are documented here.
-With some exceptions (OpenIndex,CloseIndex and KeyExists) using the index
-routines automatically positions and returns the associated record in
-the DBF database.<br><br><br>

-The locking methods return either XB_LOCK_FAILED or XB_NO_ERROR. If they return
-LOCK_FAILED the actual reason can be found in the global variable
-<em>errno</em> or function <em>perror()</em> can be executed to view the
-results.
-<br><br>
-

-successful.<br><br>

-<h3>Types of Locks</h3>
-
-<li><em>Write or Exclusive Locks</em> provide exclusive access to a
-particular file location. No other process can lock the same location.<br><br>
-
-<li><em>Read or Shared Locks</em> prohibit any process from requesting a write
-lock on a specified part of the file. Other processes can request
-simultaneous read locks.<br><br><br>
-
-<h3>DBF File Locking Techniques</h3>
-
-Xbase DBMS uses the following protocol for DBF file and record locking:
-<br><br>
-
-To lock a record - the first byte of the record is locked.<br>
-To lock the file - the header bytes of the file are locked.<br><br>
-
-When a record is being appended to the file, the header bytes are locked.<br>
-When a record is being updated, the header bytes and the specific record are
-locked.<br><br>
-This locking protocol is probably not compatable with other Xbase type products.
-However, Xbase can be safely used for multi-user access when it is not
-simultaneously updating DBF or NDX files while other products/programs are.
-<br><br><br>
-
-<h3>NDX File Locking Techniques</h3>
-
-Xbase DBMS locks indexes by locking the first 512 bytes
-of the index file.
-The entire index is locked because any updates to the index potentially
-can modify significant portions of the index tree.
-<br><br><br>
-
-<h3>DBT File Locking Techniques</h3>
-
-Xbase DBMS locks memo files by locking the first 4 bytes
-of the memo file. This effectively locks the entire file. The entire file
-is locked because any updates to the free block chain can significantly
-change the structure of the file.
-<br><br><br>
-
-
-<h3>AutoLocking Features</h3>
-
-If XB_LOCKING_ON is set in the <em>options.h</em> file, the locking methods
-execute any appropriate locking logic. If XB_LOCKING_ON is not set in the
-<em>options.h</em> file, all locking methods return NO_ERROR without
-performing any actual record or file locking. This enables the application
-program to always call locking routines regardless of the XB_LOCKING_ON switch
-in the <em>options.h</em> file.
-<br><br>
-By leaving the autolocking features enabled, the application program does
-not need to address record, file or index locking. All locking is handled
-automatically by the Xbase routines. However, if access to the locking
-routines is required, they are available to the applciation programmer.
-<br><br>
-When the files are automatically locked by the Xbase routines, the database
-file is locked first, then it locks the indexes in alphabetical order. To
-avoid deadlock conditions, files and record locks should always be done in
-the same order. When the files are unlocked, then indexes are unlocked
-first, then the database is unlocked.
-<br><br>
-Auto-locking works well in an on-line transaction based environment.
-However, it does not function efficiently in batch mode. If you
-will be writing programs which process files in a batch mode, disabling
-auto-lock and locking the entire file at the beginning of the process
-and unlocking the file at the end of the process will significantly
-reduce process time. On a 586-200 class machine, a file with 45000 records
-can be read thru in a few seconds with the file locked in batch mode.
-In record-lock mode it takes about six minutes with the same processor.
-
-<br><br>For processing large files, locking the file instead of locking each
-record is far more efficient. This is how you do it.<br><br>
-
-For reading the file in batch mode:<br>
-xbDbf.AutoLockOff();<br>
-xbDbf.LockDatabase( F_SETLKW, F_RDLCK, 0L );<br><br>
-For updating the file in batch mode:<br>
-xbDbf.AutoLockOff();<br>
-xbDbf.LockDatabase( F_SETLKW, F_WRLCK, 0L );<br><br>

-<h4>Method Descriptions</h4>
-
-<h4>Method VOID xbDbf::AutoLockOn( VOID )</h4><br>
-
-This method turns automatic record locking on. Auto record locking is on
-by default if XB_LOCKING_ON is set in the options.h file.<br><br>
-
-<h4>Example Program:</h4>
-
-See program <A HREF="/zips/loadzips.cpp">loadzips.cpp</A> for an example of
-how to use this method.
-<hr>
-
-<h4>Method VOID xbDbf::AutoLockOff( VOID )</h4><br>
-
-This method turns automatic record locking off. Auto record locking is on
-by default if XB_LOCKING_ON is set in the options.h file.
-<br><br>
-Turning auto locking off will result in slightly better execution speeds
-but should not be used in multi-user environments when multiple users can
-update files simultanteously. If multiple users are accessing a file which
-is read only then it is safe to turn off auto-locking for a particular file.
-<br><br>
-Turning autolocking off will disable any index file locking which is
-particularly dangerous in a multi-user environment if updates on the files
-are permitted.
-
-
-<h4>Example Program:</h4>
-
-See program <A HREF="/zips/loadzips.cpp">loadzips.cpp</A> for an example of
-how to use this method.
-
-<hr>
-<h4>Method SHORT xbDbf::ExclusiveLock( SHORT WaitOption )</h4>
-<h4>Method SHORT xbDbf::ExclusiveUnlock( VOID )</h4><br>
-
-ExclusiveLock and ExclusiveUnclock will lock the data file, memo file (if applicable)
-and any associated indexes in an exclusive mode. They also turn auto-lock
-on and off as appropriate.<br><br>
-
-WaitOption is either:<br><br>
-<li>F_SETLK - returns immediately regardless if success or failure<br>
-<li>F_SETLKW - waits until lock function executes<br><br>
-
-<h4>Example Program:</h4>
-
-See program <A HREF="/XbaseSamples/sample4.cpp">sample4.cpp</A> for an example of
-how to use this method.

-<h3>Method SHORT xbDbf::LockDatabase( SHORT WaitOption, SHORT LockType, LONG LRecNo )
-</h3><br>
-
-This method locks or unlocks an Xbase (.DBF) file which was previously opened.<br>
-<br>
-WaitOption is either:<br><br>
-<li>F_SETLK - returns immediately regardless if success or failure<br>
-<li>F_SETLKW - waits until lock function executes<br><br>
-
-LockType is one of:<br><br>

-<TITLE>Xbase DBMS Chapter 2</TITLE>
-<BODY BGCOLOR=#FFFFFF>
-<H2><p align="center">Database Overview</p></H2>
-<p align="center">Chapter Updated 3/18/04</p><hr>
-
-The objective of this chapter is to provide information regarding how
-the database files are utilized and document the various record structures.
-With the exception of the brief section on the record buffer, the
-information presented in this chapter is not required to use the
-Xbase library. It is mainly information describing internal file
-structures utilized by the Xbase routines.<br><br>
-
-Xbase files are comprised of a variable length header record which stores
-information about the file and describes
-the fixed length record format, followed by a series of fixed length
-data records.
-<br><br>
-
-Each fixed length data record is preceded by a one byte indicator
-which identifiies if the record has been deleted. If the record is
-not deleted, the indicator is a space (0x20). If deleted, the
-indicator contains an asterisk (0x2A). Data fields are stored in records
-without field separators or record terminators.<br><br>
-
-In earlier releases of dBASE, there is an ASCII NULL character
-between the $0D end of header indicator and the start of the data.
-This NULL was removed starting with dBASE III Plus, making a Plus
-header one byte shorter than an identically structured III file.
-The methods documented in the Xbase software and documentation follow
-the more recent version where the NULL character is not included.
-<br><br>
-
-Each database file is comprised of zero, one or many records. A record is
-comprised of fields. Only one record is accessed at a time.<br><br>
-
-Zero, one or many database files can be open simultaneously.<br><br>
-
-<hr>
-
-<h3>The Record Buffer</h3>
-
-When using the Xbase routines, each open data file has a record buffer
-which is manipulated by calling the database, index and field routines.
-
-Updates are committed from the record buffer to the database when a write,
-or append is performed. The library will automatically write updates
-to the database if the buffer has been updated and the record is
-repositioned or the database is closed.<br><br>
-
-The record buffer is not used for handling the actual data portion of
-memo fields. When working with memo fields, the application program must
-allocate enough buffer space for reading and writing memo fields.<br><br>
-
-Internal to the library, there is an additional record buffer which
-stores the original value of the data record before any changes are made.
-This is used by the index routines for finding and deleting original key
-values from any open indices before adding the new keys. If the key values
-are not changed, no index updates occur.
-
-
-<br><br>
-
-<hr>
-<br>
-<h3>Xbase Database File Header</h3>
-
-The Xbase file header, located at the beginning of the database, describes
-the .DBF database. Knowledge of this structure is not necessary to
-effectively utilize the Xbase libraries.<br><br><br>

-<hr>
-<br>
-<h3>Xbase Field Descriptor Record</h3>
-The Xbase field descriptor record stores information about each field in the
-database. Each database has from 1 to 1024 fields.
-Knowledge of this structure is not necessary to
-effectively utilize the Xbase libraries.<br><br><br>
-

-</TABLE>
-<BR><BR>
-
-<hr>
-<h3>Memo Fields</h3>
-
-Memo fields store variable length data elements in a seperate .DBT file.
-The main .DBF file maintains a ten byte field which is used by the Xbase
-routines for determining the location of the data in the .DBT file.
-<br><br>
-
-Xbase DBMS supports both dBASE III+ and dBASE IV version memo files.
-The version IV files are somewhat more efficient in that they reuse
-unused memo space when data are deleted or freed from use. With version
-III files, all new updates are appended to the end of the file and the
-unused space is not reclaimed until the datafiles are packed.
-<br><br>
-
-Memo fields can be used for storing a variety of date type. However,
-type 3 files are limited to storing textual data because most internal
-memo field processing in a type 3 file relies on two contiguous 0x1a
-charaters. <br><br>
-
-Type 4 memo fields can be used for storing BLOB (binary large object)
-data reliably, as the internal file structure does not rely on any
-special characters embedded in the data.<br><br>
-
-A special note on storing string data in a memo field. For those users
-that are new to C/C++ programming, string fields typically end with
-a null (0x00) terminator character. As a general rule of thumb when using
-the library, add one to the length of any string when
-specifying the length of the data. This stores the null terminating byte
-with the data. For example, when storing string "This is a string"
-specified size should be 17, not 16.
-
-
-<h4>Technical memo file information</h4>
-
-The following info on memo fields is for the curious.
-It is not required
-reading if you don't need to know the internals.<br><br>
-
-<li>Memo files are made up of one or more blocks
-<li>For version III files, the block size is 512
-<li>For version IV files, the block size is a multiple of 512
-<li>The minimum amout of space necessary to store one memo field is
-one block or 512 bytes.
-<li>The default block size can be adjusted by manipulating the
-XB_DBT_BLOCK_SIZE macro in the options.h file.
-
-
-<li>The main .DBF file maintains a ten byte numeric field which is blank if
-no memo data exists for a given field. Otherwise it contains a number, which
-when multiplied by the block size, points to the offset in the file of the head
-block in the file/
-<br><br>
-
-For version 3 memo field files, there are two fields in the head block of
-the file, <em>NextBlockNo</em> and <em>Version</em>. Depending on the
-Xbase software, some vendors products update these two fields, some do not.
-The Xbase library keeps the fields updated, but does not rely on them to
-be valued with correct data. This helps to support maximum compatibility
-amoungst all Xbase tools available.<br><br>
-
-For version 4 memo field files,
-the first block in the .DBT file is a header block which is comprised of
-8 bytes of data which maintain the file's block size and the next free
-block available in the file. Blocks two through n contain the actual
-memo data. A chain of empty blocks is maintained within the file for
-potential future use. When an add or update routine executes, it first
-attempts to find a spot in a set of blocks which were earlier allocated,
-but not currently in use for the data. If no free spot is found, data are
-appended to the end of the file.
-
-The free block chain is sorted in block number order. When blocks of
-data are freed and added to the free block chain, the routines will attempt
-to concatonate free block chains togethor where possible. When a delete
-occurs, or an update which requires less space occurs, the new free space
-is added to the free block chain.

-<br><br>
-<hr>
-<h3>64 Bit File Support</h3>
-Beginning with Release 3.0 of the library, Xbase was renamed to Xbase64 and
-64 bit file support was incorporated into the library.
-<br><br>
-This functionality currently works on Linux/Unix platforms which support
-64 bit file structures. 64 bit support was not tested with Windows
-because the author didn't have access to a compiler which creates 64
-bit Windows apps. If you need this functionality for Windows, consider
-donating a Windows 64 bit compiler to the project and I'll get 64 bit
-support working for Windows.
-<br><br>
-It is not advisable to use Xbase 64 bit file support in combination with
-32 bit Xbase applications such as older versions of DBase, Clipper and Foxpro.
-Xbase64 can extend the files well beyond any limits in the older 32 bit
-application development environments.
-<br><br>
-If Xbase is being built with glibc, verify it is at least version 2.2.3.

-The title of this chapter almost sounds like a popular North American
-magazine called Field and Stream. The difference between this chapter and
-that magazine is there are no dead animal carcuses or fishing lures in
-this chapter. For those you will need to get a copy of Field and Stream.
-
-<br><br>
-The main objective of this chapter is to provide information regarding the
-basic concepts of manipulating data via the field methods.<br><br>
-
-Field names can be up to ten bytes in length and can contain characters, numbers
-or special characters in the name. The field methods are used to manipulate
-the data in a record of a data file. There are several types of fields.<br><br>

-Field names, types and lengths are defined when a data file is created.
-After the file is created, the field characteristics can not be changed. To
-change field characteristics, a new database must be defined with the new
-field requirements.<br><br>
-
-<h2>Memo Fields</h2>
-
-Memo fields are variable length data fields which are stored in two parts.
-This first part is a ten byte field which is stored
-in the fixed length record of the .DBF file. The variable data is stored in
-a seperate .DBT file in 512 byte blocks. The ten byte field in the fixed
-length portion of the record points to a .DBT block number.<br><br>
-
-There are two versions of memo data files type III and type IV. Type IV
-is more advanced in that released space can be reused and it also
-supports BLOB data. The type III file is older technology, does not
-support dynamic space reclamation and only supports string data.
-See method xbDbf::SetVersion for controlling which version type you are
-using.
-
-<br><br>
-To utilize memo fields, the application program must allocate a buffer
-which is large enough to handle the memo data.<br><br>
-
-<h2>Fields and Field Numbers</h2>
-
-The Xbase routines can access field data via using field names or field
-numbers. Field numbers are numbered 0-n where the first field in a datafile
-is field 0 going through the last field n. Accessing fields by number is
-more efficient than accessing by name.<br><br>
-
-<h2>Record Schema</h2>
-
-The record schema of a file can be found in the documentation for method
-CreateDatabase in the Database Methods chapter, or view example program
-sample1.cpp.</A><br><br>
-
-<h2>Strings</h2>
-
-Beginning with Release 1.8.0a, Xbase includes support for a string class
-<em>xbString</em>. The original thinking was not to include a string
-class in the library, and encourage users to use the string class
-native to the user's compiler. But as C++ does not have a native way
-to handle strings, and there is not a standard string class across C++
-compilers, it was decided to include a lightweight string class with the
-library. In some cases this is redundant, but it is portable.
-<br><br>
-The xbString class interface was derived from the <em>Draft Standard C++
-Library by P.J. Plauger</em> and modified. If you are familiar with
-other string classes, this one should feel similar.

-<H1><p align="center">Date Processing</p></H1>
-<p align="center">Chapter Updated 2/12/99</p><hr>
-
-The objective of this chapter is to provide information regarding
-the basic concepts of date arithmetic and supply generic
-C/C++ date methods.<br><br>
-
-Two common things of all programmers is that if they write
-enough code, they will eventually have to deal with dates. They
-may be Julian dates, Gregorian dates, or a date with their best
-freind's girl, but they'll eventually be working with dates. The
-other thing is that most programmers don't have the time or don't
-want to spend time writing mundane date routines.<br><br>
-
-To explain how dates work, I'll give a brief overview and history of Julian
-dates, Gregorian dates, leap years and leap centuries.
-
-<h2>Leap Years</h2>
-
-Due to the fact that it actually takes about 365 1/4 days for
-the earth to circle the sun, every fourth year and every fourth
-century have an extra day added to the end of February and the year
-is called a leap year. Leap years have 366 days, non leap years
-have 365 days. The following code segment describes how to
-determine if a given year is a leap year.
-
-A leap year is a year having 366 days, which can be evenly
-divisible by 4 and not by 100 or divisible by 400.
-
-There are also leap centuries. Leap centuries are years which
-are evenly divisible by 400.
-
-To calculate a leap year, the following code segment can be used
-
-<xmp>
- int year;
-
- if(( year % 4 == 0 && year % 100 != 0 ) || year % 400 = 0 )
- LEAP_YEAR = TRUE;
- else
- LEAP_YEAR = FALSE
-</xmp>
-
-
-<h2>Julian Dates</h2>
-
-Around the time of Jesus Christ, a fellow with the name of Julias Ceasar
-established the Julian calendar. The Julian calendar established every
-fourth year as a leap year with 366 days and all other years having 365 days.
-The months were set up the same as they are with a Gregorian calendar, which
-is what we use today. A Julian date is defined as as the number of days from the
-first day of the year; February 1 would have a Julian day of 32.<br><br>
-
-From a programmer's perspective, Julian dates are useful for doing date
-arithmetic, determining the difference between two dates or calculating
-a future or past date.<br><br>
-
-To determine the difference between two dates, convert both dates to a
-Julian date and subtract one from the other.<br><br>
-
-To calculate a future or past date, convert the base date to a Julian date,
-add (or subtract) the number of days necessary to (from) it and convert the
-julian date back to a Gregorian date.<br><br>
-
-The Julian date routines use a base date of 01/01/1900.<br><br>
-
-<h2>Gregorian Dates</h2>
-
-In 1582, Pope Gregor XIII introduced a corrected form of the Julian calendar.
-Every 4th year still has 366 days except for century years. Century years
-were added as leap years if evenly divisible by 400. The year 2000 is a leap century.
-<br><br>
-
-The methods supplied with this software are based on gregorian dates with
-the format of CCYYMMDD for century, year, month and day.<br><br>
-
-
-<h2>CASTELLANO options</h2>
-
-There is an option in the <em>options.h</em> file for enabling the date routines
-to return Spanish values for days, weeks and months.<br><br>
-#define CASTELLANO<br><br>
-
-<h2>Date Formats</h2>
-
-All dates are stored in the .DBF files with format CCYYMMDD.<br><br>
-
-All date routines work with dates formated with the same CCYYMMDD format.<br><br>
-
-<h2>Sample Program</h2>
-
-<xmp>
-#include <iostream.h>
-#include <xbase/xbase.h>
-
-main()
-{
- xbXBase x;
- long l;
-
- cout << "\nThis program tests the XDATE routines\n\n";
-
-
- cout << "\nThis year is " << x.YearOf ( x.Sysdate() );
- cout << "\nThis Month is " << x.MonthOf( x.Sysdate() );
- cout << "\nToday is day " << x.DayOf( WEEK, x.Sysdate()) << " of the week";
- cout << "\nToday is day " << x.DayOf( MONTH, x.Sysdate()) << " of the month";
- cout << "\nToday is day " << x.DayOf( YEAR, x.Sysdate()) << " of the year";
-
- if( x.IsLeapYear( x.Sysdate()))
- cout << "\nThis is a leapyear";
- else
- cout << "\nThis is not a leap year.";
-
- cout << "\nToday is " << x.Sysdate();
-
- if( x.DateIsValid( "19951301" ))
- cout << "\n19951301 is a valid date";
- else
- cout << "\n19951301 is not a valid date";
-
- l = x.JulianDays( "19951101" ) - x.JulianDays( "19951001" );
-
- cout << "\nThere are " << l
- << " days between 10/1/95 and 11/1/95.";
-
- cout << "\nIn 7 days it will be "
- << x.JulToDate8( x.JulianDays( x.Sysdate()) + 7L );
-

-<title>Xbase DBMS Chapter 5</title>
-<body bgcolor=#FFFFFF>
-<h1><p align="center">Expression Handling<br></h1>
-<p align="center">Chapter Updated 3/12/04</p><hr>
-
-<h3>Overview</h3>
-
-The main objective of this chapter is to provide information regarding the
-basic concepts of using the Xbase Expression module.<br><br>
-
-Beginning with release 1.7.4, the Xbase library includes an expression parsing
-routine which assists application programmers by providing a high level data
-manipulation tool and also allows for building complex index keys.
-
-The functions included were derived from dBASE III Plus, but not all
-dBASE III Plus functions have been implemented yet.
-<br><br>
-Release 3.0 brought some upgrades to the expression module of the library
-including bug fixes, additional operators and new functions. The expression
-module is usable and functional, but has some room for improvement.
-A future release of Xbase will include more comprehensive expresion logic.
-
-<br><br>
-
-<h3>Internal fuctioning</h3>
-The expression module works in two phases. Firstly, method
-<em>ParseExpression</em> is called and builds an expression tree from
-all the components of the expression. The tree is made up of indivdual
-nodes. The expression is checked for valid field names, literals,
-operands and functions. Any field references are resolved. If fields
-are used in an expression and the database name for the field is not
-included in the name with the -> operand, the routines assume the
-associated database has been successfully opened.
-<br><br>
-Secondly, method <em>ProcessExpression</em> is called to process the
-expression tree created by ParseExpression(). The routine parses each
-node in the expression tree, executing functions, processing operands
-and manipulating data to produce the desired result.<br><br>
-
-If an expression will be processed repeatedely, it is best to pre-parse the
-tree using <em>ParseExpression</em>, then for each new call to the expression,
-execute method <em>ProcessExpression</em> which processes the tree.
-
-
-<h3>Expression Return Types</h3>
-Expressions will return a type of CHAR *, NUMERIC or LOGICAL.<br><br>
-
-An expression return type can be determined with method <em>
-GetExpressionResultType</em> after parsing it.<br><br>
-
-Expressions returning a return type of CHAR are limited to a 200 byte internal
-buffer. There is also a 100 byte limit for NDX index key support. If
-the 200 byte limit is not large enough for your application, adjust field
-<em>enum { WorkBufMaxLen = 200 };</em> in file <em>exp.h</em>.
-
-<h3>Expression Functions</h3>
-Each expression function also has a corresponding C++ function. It is
-slightly more efficient to call the C++ functions directly, rather than
-execute the expression parsing routines.
-
-<h3>Expression Components</h3>
-Expressions are made up of one or more tokens. A token is one of literal,
-database field, operand or function. Literals are either numeric or character.
-Character literals are enclosed in 'single' or "double" quotes. numeric
-literals are a series of one or more contiguous numerals, ".", "+" or "-'".
-<br><br>
-A field is simply a field name in the default database, or is in the form
-of database->fieldname.

-<H2><p align="center">NDX Indices</p></H2>
-<p align="center">Chapter Updated 4/12/04</p><hr>
-
-The objective of this chapter is to provide information regarding the
-basic concepts of how .NDX index files work in the Xbase environment.<br><br>
-
-The information in this chapter has been gathered by searching the internet
-and by examining the structure of known good NDX indexes.<br><br>
-
-<h4>NDX Index File Characteristics</h4>
-
-<li>NDX indices maintain keys in ascending sort order only.<br><br>
-<li>NDX indices support <em>unique</em> or <em>non unique</em> keys.<br><br>
-
-<em>Unique</em> keys must be unique. The database update routines will
-fail if an attempt to add a non-unique key is performed.<br><br>
-
-<em>Non-unique</em> Keys are not required to be unique, duplicate
-keys are allowed if the index is created with the XB_NOT_UNIQUE
-setting. Duplicate keys are stored in record number order.<br><br>
-
-<li>NDX indexes are automatically updated by the Xbase library after the
-indices are opened.<br><br>
-
-<li>Character keys are left justified and padded on the right with spaces.<br><br>
-
-<li>Numeric keys are stored as eight byte double values.<br><br>
-
-<h4>NDX File Internals</h4>
-
-NDX files are comprised of two or more 512 byte blocks or nodes of
-information. There are three types of nodes: Head Nodes, Interior
-Nodes and Leaf Nodes.<br><br>
-
-<li>The <em>Head Node</em> is the first node in the file starting at
-position zero (0) and contains information about the NDX file. There
-is only one Head Node in each index and it always starts at the
-beginning of the file.<br><br>
-
-
-<TABLE BORDER>

-The following structure is used by the Xbase NDX routines:
-<xmp>
- struct NdxHeadNode{
- xbLong StartNode; /* header node is node 0 */
- xbLong TotalNodes; /* includes header node */
- xbLong NoOfKeys; /* actual count + 1 */
- xbUShort KeyLen; /* length of key data */
- xbUShort KeysPerNode; /* max number of keys per node */
- xbUShort KeyType; /* 00 = Char, 01 = Numeric */
- xbLong KeySize; /* KeyLen + 8 */
- char Reserved1; /* Not sure about this one */
- char Unique; /* 00 = not unique, 01 = unique*/
- char KeyExpression[488]; /* key definition */
- }
-</xmp>
-<br><br>
-
-<h4>Interior and Leaf Nodes</h4>
-
-Interior Nodes and Leaf Nodes share the same structure in an NDX file.
-The difference between the two types is that interior nodes point to
-other interior nodes or leaf nodes and leaf nodes point to records in
-a DBF file. Interior nodes are optional nodes in an NDX file,
-however if there are more than a few keys in the index there will
-certainly be one or more interior nodes in the file. There will
-always be at least one leaf node in the file. Leaf nodes contain DBF
-record numbers which point to the location of the record in the
-DBF file.<br><br>
-
-Interior nodes have field LeftNodeNo valued which points to the node
-which points to the keys which are less than the key value in the KeyVal
-field. There is one more LeftNodeNo value in the node than there are keys.
-The Last LeftNodeNo points to the node which is greater than the highest
-key value in the node. Interior nodes have 0 in the value for the
-DbfRecNo field.<br><br>
-
-Leaf nodes have 0 in the LeftNodeNo field but do have a value in the
-DbfRecNo field which points to a DFB record.<br><br>

-
-<br><br>
-For those interested in knowing how the Xbase DBMS manipulates and
-navigates index files, the following discussion may be helpfull.<br><br>
-
-Xbase DBMS navigates through NDX files by using an in-memory chain
-of nodes of the current location / key in use. It starts by reading the
-Head Node of the index, which points to the first node of the file. The
-first node of the file will be a leaf node if the index is small or will
-be an interior node if the index has more than one leaf node. The first
-interior node is loaded into memory, added to the node chain and points
-to the next node to read. The node is made up of one or more keys. If
-it is a leaf node, the logic looks for a matching key on the node.
-Otherwise, if it is an interior node, the logic looks at the keys until the
-search key is greater than or equal to the key in the node and then
-traverses down the tree to the next node. It continues down the tree,
-adding the nodes to the in-memory node chain until it reaches the correct
-leaf node. If it finds a matching key in the leaf node, it returns a
-XB_FOUND condition. If it doesn't find an exact match in the leaf node, it
-returns a XB_NOT_FOUND condition and stops on the key which is greater than
-the search key given.

-<h4>Interior and Leaf Nodes</h4>
-
-NTX files use a B-tree system to store keys. A B-tree is a balanced,
-on disk tree who's design minimizes disk access. Interior Nodes and
-Leaf Nodes share the same structure in an NTX file. The difference is
-that interior nodes point to other nodes. Leaf nodes point to
-nothing. Keys in both interior nodes and leaf nodes point to records
-in a DBF file.
-
-Interior nodes have field LeftNodeNo valued which points to the node
-which points to the keys which are less than the key value in the KeyVal
-field. There is one more LeftNodeNo value in the node than there are keys. The
-Last LeftNodeNo points to the node which is greater than the highest
-key value in the node. <br><br>
-
-Leaf nodes have 0 in the LeftNodeNo field.<br><br>

-One primary difference between NDX files and NTX files is that NTX
-files uses an array of offsets on all interior and leaf nodes. Each
-offset is the byte count from the beginning of the node where each
-KeyRec will be found. The order of the array of offsets determines
-the order of keys on a given node. When keys are added or deleted,
-thus changing the order of the keys on a node, only the order of the
-offset array is changed. All other key data is not moved. This results
-in slightly better index performance.

-<H1><p align="center">Record and File Locking</p></H1>
-<p align="center">Chapter Updated 2/1/99</p><hr>
-
-<h3>Locking Overview</h3>
-
-Xbase DBMS supports multi-user processing through file and record locks.
-Record locking restricts multiple cooperating programs from simultaneously
-accessing the same data and corrupting it. Without record and file locking
-in a multi-user environment, simultaneous access to the data and index files
-can cause the files to become inaccurate and unusable.<br><br>
-
-Record locking is on by default in the Xbase DBMS library. To disable it,
-comment out the XB_LOCKING_ON option in the <em>options.h</em> file in the
-xbase/src directory.<br><br>
-
-The current Xbase DBMS record locking does not co-exist with other Xbase
-products and there is not yet support for locking in a DOS/Windows environment.
-The locking functions do work correctly for a Xbase DBMS only configuration.
-Future version of Xbase DBMS will have enhanced locking features for
-co-existing with other Xbase products and also include DOS/Windows support.
-<br><br>
-
-The locking methods return either XB_LOCK_FAILED or XB_NO_ERROR. If they return
-XB_LOCK_FAILED the actual reason can be found in the global variable
-<em>errno</em> or function <em>perror()</em> can be executed to view the
-results.
-<br><br>
-
-The errno field may contain one of the following values if the lock was not
-successful.<br><br>

-</TABLE>
-<br><br>
-<h3>Types of Locks</h3>
-
-<li><em>Write or Exclusive Locks</em> provide exclusive access to a
-particular file location. No other process can lock the same location.<br><br>
-
-<li><em>Read or Shared Locks</em> prohibit any process from requesting a write
-lock on a specified part of the file. Other processes can request
-simultaneous read locks.<br><br><br>
-
-<h3>DBF File Locking Techniques</h3>
-
-Xbase DBMS uses the following protocol for DBF file and record locking:
-<br><br>
-
-To lock a record - the first byte of the record is locked.<br>
-To lock the file - the header bytes of the file are locked.<br><br>
-
-When a record is being appended to the file, the header bytes are locked.<br>
-When a record is being updated, the header bytes and the specific record are
-locked.<br><br>
-This locking protocol is probably not compatable with other Xbase type products.
-However, Xbase can be safely used for multi-user access when it is not
-simultaneously updating DBF or NDX files while other products/programs are.
-<br><br><br>
-
-<h3>NDX File Locking Techniques</h3>
-
-Xbase DBMS locks indexes by locking the first 512 bytes
-of the index file.
-The entire index is locked because any updates to the index potentially
-can modify significant portions of the index tree.
-<br><br><br>
-
-<h3>DBT File Locking Techniques</h3>
-
-Xbase DBMS locks memo files by locking the first 4 bytes
-of the memo file. This effectively locks the entire file. The entire file
-is locked because any updates to the free block chain can significantly
-change the structure of the file.
-<br><br><br>
-
-
-<h3>AutoLocking Features</h3>
-
-If XB_LOCKING_ON is set in the <em>options.h</em> file, the locking methods
-execute any appropriate locking logic. If XB_LOCKING_ON is not set in the
-<em>options.h</em> file, all locking methods return XB_NO_ERROR without
-performing any actual record or file locking. This enables the application
-program to always call locking routines regardless of the XB_LOCKING_ON switch
-in the <em>options.h</em> file.
-<br><br>
-By leaving the autolocking features enabled, the application program does
-not need to address record, file or index locking. All locking is handled
-automatically by the Xbase routines. However, if access to the locking
-routines is required, they are available to the applciation programmer.
-<br><br>
-When the files are automatically locked by the Xbase routines, the database
-file is locked first, then it locks the indexes in alphabetical order. To
-avoid deadlock conditions, files and record locks should always be done in
-the same order. When the files are unlocked, then indexes are unlocked
-first, then the database is unlocked.
-<br><br>
-Auto-locking works well in an on-line transaction based environment.
-However, it does not function efficiently in batch mode. If you
-will be writing programs which process files in a batch mode, disabling
-auto-lock and locking the entire file at the beginning of the process
-and unlocking the file at the end of the process will significantly
-reduce process time. On a 586-200 class machine, a file with 45000 records
-can be read thru in a few seconds with the file locked in batch mode.
-In record-lock mode it takes about six minutes with the same processor.
-
-<br><br>For processing large files, locking the file instead of locking each
-record is far more efficient. This is how you do it.<br><br>
-
-For reading the file in batch mode:<br>
-xbDbf.AutoLockOff();<br>
-xbDbf.LockDatabase( F_SETLKW, F_RDLCK, 0L );<br><br>
-For updating the file in batch mode:<br>
-xbDbf.AutoLockOff();<br>
-xbDbf.LockDatabase( F_SETLKW, F_WRLCK, 0L );<br><br>

-
-<h3>Locking Overview</h3>
-
-Xbase DBMS supports multi-user processing through file and record locks.
-Record locking restricts multiple cooperating programs from simultaneously
-accessing the same data and corrupting it. Without record and file locking
-in a multi-user environment, simultaneous access to the data and index files
-can cause the files to become inaccurate and unusable.<br><br>
-
-Record locking is on by default in the Xbase DBMS library. To disable it,
-comment out the LOCKING_ON option in the <em>options.h</em> file in the
-xbase/src directory.<br><br>
-
-The current Xbase DBMS record locking does not co-exist with other Xbase
-products and there is not yet support for locking in a DOS/Windows environment.
-The locking functions do work correctly for a Xbase DBMS only configuration.
-Future version of Xbase DBMS will have enhanced locking features for
-co-existing with other Xbase products and also include DOS/Windows support.
-<br><br>
-
-The locking methods return either LOCK_FAILED or NO_ERROR. If they return
-LOCK_FAILED the actual reason can be found in the global variable
-<em>errno</em> or function <em>perror()</em> can be executed to view the
-results.
-<br><br>
-
-The errno field may contain one of the following values if the lock was not
-successful.<br><br>

-<h3>Types of Locks</h3>
-
-<li><em>Write or Exclusive Locks</em> provide exclusive access to a
-particular file location. No other process can lock the same location.<br><br>
-
-<li><em>Read or Shared Locks</em> prohibit any process from requesting a write
-lock on a specified part of the file. Other processes can request
-simultaneous read locks.<br><br><br>
-
-<h3>DBF File Locking Techniques</h3>
-
-Xbase DBMS uses the following protocol for DBF file and record locking:
-<br><br>
-
-To lock a record - the first byte of the record is locked.<br>
-To lock the file - the header bytes of the file are locked.<br><br>
-
-When a record is being appended to the file, the header bytes are locked.<br>
-When a record is being updated, the header bytes and the specific record are
-locked.<br><br>
-This locking protocol is probably not compatable with other Xbase type products.
-However, Xbase can be safely used for multi-user access when it is not
-simultaneously updating DBF or NDX files while other products/programs are.
-<br><br><br>
-
-<h3>NDX File Locking Techniques</h3>
-
-Xbase DBMS locks indexes by locking the first 512 bytes
-of the index file.
-The entire index is locked because any updates to the index potentially
-can modify significant portions of the index tree.
-<br><br><br>
-
-<h3>DBT File Locking Techniques</h3>
-
-Xbase DBMS locks memo files by locking the first 4 bytes
-of the memo file. This effectively locks the entire file. The entire file
-is locked because any updates to the free block chain can significantly
-change the structure of the file.
-<br><br><br>
-
-
-<h3>AutoLocking Features</h3>
-
-If LOCKING_ON is set in the <em>options.h</em> file, the locking methods
-execute any appropriate locking logic. If LOCKING_ON is not set in the
-<em>options.h</em> file, all locking methods return NO_ERROR without
-performing any actual record or file locking. This enables the application
-program to always call locking routines regardless of the LOCKING_ON switch
-in the <em>options.h</em> file.
-<br><br>
-By leaving the autolocking features enabled, the application program does
-not need to address record, file or index locking. All locking is handled
-automatically by the Xbase routines. However, if access to the locking
-routines is required, they are available to the applciation programmer.
-<br><br>
-When the files are automatically locked by the Xbase routines, the database
-file is locked first, then it locks the indexes in alphabetical order. To
-avoid deadlock conditions, files and record locks should always be done in
-the same order. When the files are unlocked, then indexes are unlocked
-first, then the database is unlocked.
-<br><br>
-Auto-locking works well in an on-line transaction based environment.
-However, it does not function efficiently in batch mode. If you

-
-For reading the file in batch mode:<br>
-DBF.AutoLockOff();<br>
-DBF.LockDatabase( F_SETLKW, F_RDLCK, 0L );<br><br>
-For updating the file in batch mode:<br>
-DBF.AutoLockOff();<br>
-DBF.LockDatabase( F_SETLKW, F_WRLCK, 0L );<br><br>

-<h4>Method Descriptions</h4>
-
-<h4>Method VOID DBF::AutoLockOn( VOID )</h4><br>
-
-This method turns automatic record locking on. Auto record locking is on
-by default if LOCKING_ON is set in the options.h file.<br><br>
-
-<h4>Example Program:</h4>
-
-See program <A HREF="/zips/loadzips.cpp">loadzips.cpp</A> for an example of
-how to use this method.
-<hr>
-
-<h4>Method VOID DBF::AutoLockOff( VOID )</h4><br>
-
-This method turns automatic record locking off. Auto record locking is on
-by default if LOCKING_ON is set in the options.h file.
-<br><br>
-Turning auto locking off will result in slightly better execution speeds
-but should not be used in multi-user environments when multiple users can
-update files simultanteously. If multiple users are accessing a file which
-is read only then it is safe to turn off auto-locking for a particular file.
-<br><br>
-Turning autolocking off will disable any index file locking which is
-particularly dangerous in a multi-user environment if updates on the files
-are permitted.
-
-
-<h4>Example Program:</h4>
-
-See program <A HREF="/zips/loadzips.cpp">loadzips.cpp</A> for an example of
-how to use this method.
