Re: monmsg in clp pgm questions

Hello David, and Kerwin,

Funny, this doesn't look like RPG to me!  However, it is possible to monitor 
for *DIAG 
messages if the command processing program has been properly written.

CPYF is one of the few IBM commands that uses diagnostic messages properly.  
CPYF sends a 
single *ESCAPE message and supplies the message ID of the diagnostic message in 
the message 
data.  You can simply compare the message data and execute the appropriate 
block of code.  
There are 93 or so possible *DIAG message IDs sent prior to the CPF2817 *ESCAPE 
message.

While receiving the diagnostic messages will work, the proper method in this 
case is to use 
the CMPDTA keyword and get the MONMSG to test for the specific *DIAG message.  
So your code 
should look like:

 CPYF       FROMFILE(FROMLIB/FROMFILE) +                  
              TOFILE(TOLIB/TOFILE) FROMMBR(*FIRST) +    
              TOMBR(*FIRST) MBROPT(*REPLACE) CRTFILE(*NO) 
 MONMSG     MSGID(CPF2817) CMPDTA(CPF2869) EXEC(DO)
   /* Handle empty from-file */
 ENDDO
 MONMSG     MSGID(CPF2817) CMPDTA(CPF2861) EXEC(DO)
   /* Handle whatever */
 ENDDO
 MONMSG     MSGID(CPF0000) EXEC(DO)
   /* Handle anything else */
 ENDDO

The final MONMSG for CPF0000 should really be caught by your global exception 
handler.  And 
the less said about that GOTO monstrosity you used the better!!!!

See the Data Management Guide (Chapter 4.1.4) for more information.

Simon Coulter.
