Thanks everyone for your replies. They're very helpful! I think I won't
use recursion in production RPG when a loop will do.

It has been awhile, and perhaps I am misremembering (the little gray cells

hung;
i.e., shouldn't have taken more than a few second to run, but was still
running after I got back from lunch. Went into debug and it was hung in a
procedure where I had forgotten to put a RETURN. Just sat there asking,
"Okay, what the heck am I supposed to do now.

If you have an RPG program that uses the cycle (even implicitly) and
the program neither does a return nor ends a cycle with LR on, it will
start a new cycle. (The compiler ensures that the program contains an
exit mechanism but can't ensure that it will ever actually execute.)

But that's not true of procedures because they don't have the cycle.

However if a program whiche is running forever because the cycle issue
calls a procedure, it very well could be in that procedure when you
look at it.
