The input argument is consumed by the DO. Wow, the troll discusses Forth, gets one correct, and isn't calling someone else a troll. What's even more notable is that she (IIRC) pointed out to me, and either Andrew or Mark, maybe about a year and half ago, that if our loop control words were coded correctly then they shouldn't need DROPs or 2DROPs at the end. Yet, she used a DROP after a loop. Rod Pemberton
