I presume you are talking about the data/parameter stack.  My question would
be how large to make the return stack.  It seems to me that since Forth
words get nested pretty deep, you would want a sizable return stack, maybe
even bigger than the data stack.

I'm a newbie to Forth, so no flames please.
