I am just starting out using Forth and was wondering if MacForth allows
recursion and if anyone has examples if it does.

Tom:
	Yes it does.  Here is an example (factorial -- what else :):

: FACTORIAL  ( n1 -- n2)	\ return n1 factorial
   ?DUP IF  DUP 1-  MYSELF *  ELSE  1  THEN ;


	As you can probably tell, MYSELF invokes the word which is being
compiled, i.e., it recurses.
