I agree that a patch to the HCP command to check that it's
running under Hercules would be a good idea.
FWIW, I agree.
I also think there's an argument that a Hercules console
message for illegal DIAGNOSE instructions could be helpful
in the presumably rare case where an OS performs a DIAGNOSE
instruction incorrectly, and it does seem easy to implement.
We already have that:

If you're not seeing the above messages on your Hercules console, then it's probably because you're using the wrong OSTAILOR setting (such as the stupid and NOT recommended OSTAILOR QUIET setting, which we've discussed to death on this forum before).
