Please help with a test (MI code)

The following RPG program generates the TSTPROC Mi-program
that when run will send a message to the requesters msg-q showing
the processor serial number (NOT the system serial number).
I'm trying to see if the result is predictable. It could be version
dependent.
It works on RISC V4R3. On CISC boxes I expect to get a result of
X'00' s, but would like help with testing of this on various boxes,
RISC, CISC, various releases.
