<p align="center">Page Updated 2/19/04</p><hr>
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.<br><br>
