You can use a CALL(E) or CALLP(E) on the call to QCMDEXC to stop it
blowing up your program.
    callp(e)  qcmdexc(cmd : %len(cmd));
    if %error;
      ...

(Broken-record alert) I prefer QCMDEXC() to system() because QCMDEXC()
leaves the exception message in the joblog, which makes it much easier
to debug in cases where you get an unexpected exception.  With system(),
you only get the message ID, you don't get the replacement values.  And
once your program has ended, you don't even have the message id unless
you logged it somewhere.
