It +was removed from the core classes because it would be incompatible with +later versions of the xbase file structures. If you were interested in +adding this back into the library, you could derive a new dbf class +and add the mods into the new derived class, leaving the base class +as it stands. + + +To add additional memo functionality, create a new derived class from +the xbMemo class. + + + +Update xbFile::DetermineXbaseVersion to identify Xbase file type \ No newline at end of file -- cgit v1.2.3
