The problem I always have with using a subprocedure as a wrapper for
QCMDEXC is the call level.   When I do an OVRDBF or similar command
via my subprocedure, it doesn't work because its at a different call
level.

Sure, I could do OVRSCOPE(*JOB)  but thats not a very elegant solution!

So, I usually do a prototype with a CONST parameter for the command and
the length.  Then I can do something like this:

C               callp     Cmd('OVRDBF FILE(FILEONE) TOFILE(FILETWO)': 200)

I would certainly PREFER to not pass the length -- but havent found a good
way.   What am I missing?
