Recursive Calls

I'm curious about how most people handle possible recursive calling
situations.
We're running V4R1 and coding in RPG/ILE.  We have a situation where program
A
is called from a menu.  Program A creates a workorder and then calls Program
B,
the workorder maintenance program.  From the workorder maintenance program,
one can use F6 to create another workorder, thus calling Program A.

So, the questions:  When Program A calls Program B, can I remove it from the
program stack?  Can Program B remove it from the stack when it realizes
that Program A needs to be called?  If program B can remove Program A from
the stack, what happens when Program B ends and Program A is no longer
there to go back to?  If any of this can be done, which manual outlines how
this is done?

Thanks in advance,
