David,
Have you ever had this happen? QCMDEXC should not change the call level.
Commands are run at the level of the caller. There should be no problem if you
place the procedure in a program or service program that specifies
ACTGRP(*CALLER). The default value for ovrscope is *ACTGRPDFN. For
example your ILE program which runs in a named activation group QILE calls
your new subprocedure ExecuteCmd which is in a service program that specifies
caller. If an override command is passed that specifies the default value for
OVRSCOPE(*ACTGRPDFN) . Your override will affect all file opens done
by any program running in the activation group QILE.
The problem you describe should only happen for programs running in the default
activation group. This is because *ACTGRPDFN is converted to *CALLLVL in
this case.
I have not used our procedure to execute override commands, but if overrides
use *CALLLVL because QCMDEXC is an OPM program I would say that is a bug,
or IBM should provide an CEE4 equivalent. QCMDEXC is supposed to be
transparent to the command that is executed. Let me know if you have
experienced
otherwise. If I get a few minutes I will test with an override and let you
know what I
find.
Thanks

Of course you realize that this doesn't work when the command you want
to execute is an override (OVRDBF, OVRPRTF, etc.) unless you use
OVRSCOPE(*JOB), which can be risky.
