Joe,

coding subrpocedure or function that is going to be called recursively
or autorecursively, you have to take care about "exit condition". Your
subprocedure or function must "know" when to "move back". Maximum number
of possible recursions depends of available memory and processor and few
other things, but I was going as deep as 20000 call stack entries.

BTW, thanks ppl. in RPG research labs for making that wonderful
mathematical principal avilable in RPG, our job became much more
interesting since.
