Re: QMHSNDPM in serviceprogram

An approach I've taken in my message handling *SRVPGM is to specify a call
stack entry value of *PGMBDY and and a call stack entry qualification value
of '*NONE ' + the name of my caller. I use the Retrieve Call Stack
(QWVRCSTK) API to determine the name of my caller. This seems to work
pretty well (or at least no one has complained).

Hi Scott,

Yes, I used something like that as well. But instead of counting the call
stack entries I had the caller pass its name (from the PSDS) as a
parameter, so the call to QMHSNDPM can use *PGMNAME with the call stack
entry qualification parameter.

Hi there Joep,

Yes, that has always been a dilemna for me as well. Unfortunately,

there's no perfect solution. In some applications using *PGMBDY 1 works
nicely -- because I want to send to whomever called my service program.

But, for the other circumstance where I have a "send error" utility

called from a program, and I want to send to that program's caller, there's
no easy solution. The best I've come up with is to accept a parameter with
the number of call stack levels. So the "send error" procedure accepts
this parameter, and uses call stack '*' and call stack count is the
parameter. That way, my program can specify 2, 3, 4... whatever it needs
to go to the level that program desires.

Of course, that's clumsy because I have to count the call stack levels,

etc, but it's the best I've found.

*CTLBDY could work nicely if you always use ACTGRP(*NEW) (or in some

other way put every program in a diff activation group) -- but there are
many circumstances where this isn't practical, either.
