Thanks very much for your reply, Alex. I only have a few minutes to post but I
can reply to some of these :)
4 - Is it permissible to include declarations of that type inside a word
definition that's using the local variable syntax? I did want to put a
description of the quotation into the stack effect but I wasn't sure if I could
do it while at the same time giving the local variable holding the quotation a
name. In your example, is the quotation variable named "quot"?
5 - It's the Bresenham linedraw code taken from the Wikipedia page; the final
