Re: receiving message from QSYSOPR msgq

Sorry, I mixed answer and question and made a mess of the question.
I should have asked: So the MSGID retrieved in this particular code is
evertime just only the last one that has been put on the message queue?
And if I want to take the one before the last retrieved I should use *PRV if
I started with *LAST. Is that right?

Thanks,
Arco Simonse

However, I see my assumption of the working of RCVMSG is bad. I
thought that giving the MSGID as parameter to the RCVMSG would be
sufficient to receive the last message with that id.

I'll study that part again...

The MSGID() parameter of RCVMSG is a /return value/ only; i.e.
the value of the variable &MSGID when a request is made to RCVMSG
MSGQ(QSYSOPR) MSGTYPE(*INFO) RMV(*NO) MSGID(&MSGID) does not effect
any /selection/ across the available informational messages.

Supposing the parameter could effect selection, then there would
be little reason to follow that request with the condition logic of
IF COND(&MSGID *NE 'CPF0968') THEN(DO), but if the effect of RCVMSG
with selection could change the value, then the code should have
done CHGVAR &MSGID 'CPF0968' before retry anyhow.
