Currently, I query the outfile of DSPPGMREF *ALL to what calls program A,
and drill backwards until I get no results. And, by "drill backwards", I
mean that I manually query each one. I.e., if program A is called by
programs B and C, then I run the same query for B and for C. Obviously,
for deeply nested calls, this can be an onerous exercise.

I know there are commercial products available, but these are not options
for me.

I'm wondering if there's a way to write a query that does this "recursion"
(?) for me. Thinking of a "Bill of Materials" type of report, I guess.
