Nope, working as designed.

Don't know if an exit program exists, but if it does you could use that.

Repeat after me, "menu security" i.e. depending on a fixed set of menus and
the LMTCAP(*YES) to restrict access is not a valid solution in today's
environment.

You need a properly designed and implemented security model using OS/400's
object oriented security.

If your programmers shouldn't be allowed to do a WRKACTJOB, then they
shouldn't have authority to the WRKACTJOB command.
