Then that program is responsible for not creating any security

Is that program written to work properly with that parameter? If not,
then the AC(1) program has an integrity violation for calling it.

I would consider that to be a bug and at best to be more surprising
than only testing the length. There's nothing in the string "LONGPARM"
to suggest that it applies to short parm data.
