     In my CLLE program, I use the following command:

     Occasionally, one of the controllers will fail to vary off due to
     CPA2611 (Sender copy).  This message is not monitor-able.  It requires a
     reply, either 'C' or 'G'.  I set up the system reply list to reply with
     'C'.  That is working.  But now I want to capture the error in the
     program to do other things based on that message.  FWIW, after the reply
     is sent, another message appears in the job log, CPD27EE (Diagnostic),
     which is the same message as CPA2611.
     I've tried:
     1) RCVMSG     MSGDTA(&MSGDTA) MSGDTALEN(&MSGDTALEN) MSGID(&MSGID)
     2) RCVMSG     PGMQ(*PRV) MSGDTA(&MSGDTA) MSGDTALEN(&MSGDTALEN)
     MSGID(&MSGID)
     followed by
     If         (     &MsgID = 'CPA2611' +
                 *or &MsgID = 'CPD27EE')  Then( Do )
      ChgVar     &VryOffErr '1'
      ChgVar     &WrkCfgSts '*YES'
     Enddo
     ... but this never triggers.
     It's been a very long time since I last worked with program message
     queues.  I have a vague recollection that the program may need to
     receive multiple messages from the queue to find the one I'm looking
     for.  But, before I went down the rabbit hole, I wanted to ask this fine
     body of exceptional professional developers.
