Hi Jack,
I think that's the problem... I want the conversion (expansion of the
JCL proc) to be done on one system and THEN submit the expanded result
to another system for actual execution.

An example is...
- A VM user runs an exec to process data from a magnetic tape.
- The exec on VM knows on which MVS system to run the job based on
tape vol ser. (Tapes with prefix A go to MVS A, tapes with prefix B go
to MVS B, etc.)
- The JCL PROC is maintained on MVS A
- Send the JCL to MVS A with "something" that says, after expanding
the PROC, execute the resulting job stream on MVS x

This should include any DD */DD DATA inline data as well, and the same
JOB card should be sent.

As far as I can tell, that's (almost) exactly what /*XMIT does... thek
iccker being that /*XMIT sends the JCL to the other system BEFORE
expanding any JCL procs. DOH! :-)

We do use SYSAFF in some cases... MVSA for exa,ple is actually two
systems with (almost) shared "everything". Some jobs require the
sysaffinity. But If I submit a JOB to MVSA (which could actually run
on MVSA or MVSA1 if no SYSAFF is coded) and I specify SYSAFF=MVSB,
which is in a different city.... will that accomplish what I want?

I can try it easily enough. But I didn't think that would do it either.
