happy to send the entire service program if you are interested.

Mine looks for specific programs in the stack, and it reads the whole
stack. I do however look at the library of the program in the stack, and
throw out any that are in QSYS. Not sure if that would help or not. I would
think something like the below would work.

Pseudo code

getnext = false;
Read Stack Entry.
If entry = trigger program;
Getnext = true;
Endif;
if getnext = true and entry.library <> 'QSYS';
Return thisentry;
Endif;
repeat your loop.

Does anyone have a program that's getting "who called me" for a trigger?
I've tried several versions that are available on line. The one I'm
currently using is returning QRNXIO for many of the transactions. I guess
it's crawling back too far.

Thanks, Art
