MONMSG not monitoring

["Tom Jedrzejewicz @ San Pedro" <TJedrzejewicz@xxxxxxxxxxxx>]

Folks -- model 820 V5R1

The following code is run from the console daily for our backup . . .
DLYJOB     RSMTIME('23:30:00') 
ENDSYS     DELAY(120)          
MONMSG     MSGID(CPF0000)      
DLYJOB     DLY(180)            
INZTAP     DEV(TAP01) NEWVOL(DAILY) NEWOWNID(CFP) +
             CHECK(*NO)                            
MONMSG     MSGID(CPF0000 CPA0000)
DLYJOB     DLY(60)
--> followed by the various save commands
STRSBS     SBSD(QCTL)  

occasionally there will be a problem with the tape, or a failure to put
one in, or a write-protected tape.  Last night, the INZTAP failed, and
the system waited for .  The following message was in the log.

 Message . . . . :   Device TAP01 was not ready or next volume was not
loaded.  
   (C R)                                                               
        
 Cause . . . . . :   Either the device TAP01 is not ready or the next
tape      
   volume is not loaded on TAP01.                                      
        
 Recovery  . . . :   Do one of the following:                          
        
     -- Type C to cancel processing.                                   
        
     -- Make device TAP01 ready, and type R to try the open operation
again.    
     -- Put the next volume on device TAP01, and type R to try the open
        
   operation again.                                                    
         

My question is . .  why did the MONMSG on the INZTAP not trap this
error and continue on?  I want to add code to have an email generated,
but if the error is not caught that code is useless.

TIA -- Tom J.
