  What is the difference between FOR/NEXT and DO/LOOP?  Don't they do the

FOR NEXT was conceived as a bare-bones loop that down-counts to zero.
DO LOOP is more flexible.  While Moore was prepared to throw out the
latter's features for a simpler implementation in microcode, it's fair
to say most forthers were not.
