Beginning with release 1.8.0a, error processing can be handled using exception
processing, or by checking the functions return codes. If you choose exception
processing, you will need to compile in the option to do so when you build
the library. To see an example of how to use exception processing, examine
program dumprecs.cpp. <br><br>
If you are not using exception processing, 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>
