Xbase Return Codes

Page Updated 2/19/04

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 value which corresponds to a value in this table.
