message: This does not seem to be an appropriate use for 'recursive call's. 
Even though RPGLE can be called recursively there is no need to do this. The 
'PAG' grows infinitely. If you don't want the user to press F12 'infinitely' 
number of times you must code some sort of 'F3-passthrough', and then you could 
as well do it the nice way with a driver program: Call Program A and recieve 
'what to call next' when A returns. Including 'what to call next' you should 
keep track of which programs that needs to be terminated just before your 
driverprogram ends as you might have chosen to return from Program A without LR.

This driverprogram might be your menu system top-program. Another simple 
approach (if all 'Program A'/'B's are CL-programs) is to let all of them end 
with an TFRCTL instead of RETURN.
