Re: Parameter issues using QMHSNDPM API

SNDPGMMSG from a CL program *should* work. Unlike the QMHSNDPM API, the
SNDPGMMSG command is capable of sending non-program messages. (Don't
ask me why or how IBM decided to use a command named "Send Program
Message" to send non-program messages -- but they did.)

Because:
a) It is sending from a program
b) It is only usable in a program

Perhaps is just a conceptual thing but seems to me that SNDMSG is intended for use from the command line (or menu) and SNDPGMMSG is intended for use from within a CL program thus the PGM part refers to where it originates rather than where the message is sent. Compare with QMHSNDM and QMHSNDPM which seem to refer to the target (either explicitly or implicitly) rather than the source.

The message you send to QSYSOPR cannot be an *ESCAPE message (no matter
how you send it) and that might be why your CL program is failing.

Actually, you can send *ESCAPE messages to a non-program message queue--although there seems little point since it can't be monitored and won't behave like an *ESCAPE message.
