Title: RE: MCH3402

Unfortunately, there are many other programs being called in the job.  It's an "async" job which waits for an entry to hit a data queue and then calls other programs with the data received.  Looks like I could be in for a long hunt here.

Thanks for the reply,

        Are ANY,  I mean ANY other programs being called within this job
stream ??
        Don't look at just these two and think you looked everywhere.

        For example,

        PGMA  calls PGMB
        PGMB  returns to PGMA

        sometime later

        PGMA calls PGMC
        PGMC  returns to PGMA

        Sometime later

        PGMA calls PGMB
        PGMB returns to PGMA

        PGMA goes down for a MCH  error.

        Who's fault ??   PGMC stepped on the
        PSSA or Working Variables area of
        PGMA without PGMB knowing it,   It
        wasn't a problem till PGMA tried to
        refer to those variables(or other things
        like program names, parms, etc)
        that it discovered someone TOASTED
        PGMA's area.

        It probably isn't PGMA,  nor PGMB
        but someother program in the stack
        that may or may not logically be called every time.

        What makes it worse is that you could
        run it many times without PGMA happening
        to refer to the particular area that got stepped
        on, or the problem program being called.

        But. I'd be willing to bet that  It's a mismatched parm somewhere.

        You have to look at EVERY program that may logically
        be called.

        Okay, I'm stumped.  I know that Hans has said when these MCH errors
occur, it's usually not the operating system but a bug in a user program. 
Well, we have 2 programs that get these (only once and a while though) and
I've been on a hunt to find the culprit but have been unable.

        I've checked all the parameters of the calling and receiving
programs and they match.  I'm at a loss.  What other things should I be
looking for?
