Re: Command validation program

["Simon Coulter" <shc@xxxxxxxxxxxxxxxxx>]

Hello Vanya,

Commands are a special form of message.  They are request messages (hence a 
program, such as QCMD, which 
processes commands is a request processor -- these sorts of programs are the 
ones that CNLRQS works on).

You should be able to retrieve the most recent *RQS message from the joblog.  
For example:

RCVMSG PGMQ(*PRV) MSGTYPE(*RQS) MSG(&CMD)
IF (%SST(&CMD 1 5) *EQ 'MYCMD') DO
   /* some stuff */
ENDDO

This will get the first new request message from the previous program queue 
which should be the one you are 
after.  You may need to loop forward, checking for the commands you are after 
but each processed request 
message should be marked old by its request processor.

I cannot test this for you at the moment but I have done this in the past so I 
know it works.  You may have to 
play with the various values for MSGTYPE and MSGKEY, 

Regards,
Simon Coulter.
