RE: QCMDEXC UDF Was: journal receiver maintenance

Rob,

I'm confused, are you stating that QCMDEXEC does not supply a return code?
Or is this only in certain cases?

From the IBM doc.

If an error is detected while a command is being processed through the QCMDEXC program, an escape message is sent. You can monitor for this escape message in your CL procedure or program using the Monitor Message (MONMSG) command.

If a syntax error is detected, message CPF0006 is sent. If an error is detected during the processing of a command, any escape message sent by the command is returned by the QCMDEXC program. You monitor for messages from commands run through the QCMDEXC program in the same way you monitor for messages from commands contained in CL procedures and programs.

See the appropriate high-level language reference book for information about how high-level language programs handle errors on calls.

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 http://www-01.ibm.com/support/knowledgecenter/ssw_ibm_i_72/rzajq/rzajqprocqcmdexc.htm?lang=en

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.
