I think your coworker is correct. Is this not how a service program
works?

recursive calls
Hi all
Today, by accident I set up a job where program tried to call itself. We
have one program that is duplicated in several libraries and LIBA/PGM
should have called LIBB/PGM. This was the first time I'd actually seen the
error produce in this way. A coworker informed me that recursive calls
were possible with subprocedures thanks to the fact that at each call, a
separate storage area is allocated for each subprocedure. This is not the
case for program calls. That means that if mySP calls mySP and there is a
local variable V1, there will be two adresses for V1, each containing a
different value.
I don't doubt my coworker, it's just that my reference is midrange.com.
Is my information accurate? What happens to static variables in such
subprocedure calls?
