The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
What would one expect to see as a return code from a QCMDEXC UDF?
0 for failure, 1 for success?
null for success, 7 character message id for failure?
The QCMDEXC stored procedure currently has no return value

Granted, the return value may not fit for 'every' situation, nor may it
provide enough detail to resolve every situation, but it just might be
enough to say unexpected results occurred, look further if you need
further information.
You're right, system() often doesn't supply enough information and I do
prefer some of the other APIs. However, that doesn't stop a LOT of people
from using it. Are we supposed to force our belief that one should never
use system() but instead use one of the much more complicated APIs.
