I don't like system() because it removes the final escape message from the joblog. If you get an unexpected exception, the only thing you can get from _EXCP_MSGID is the message ID. Any substitution values are lost.

Also, system() doesn't remove any diagnostic messages that precede the final escape message. That can make the joblog look very strange if something bad happens.

For me, the extra coding for QCMDEXC or QCAPCMD is worth it to get a good joblog if something unexpected happens.
