Subject: Re: Two DO questions From: Erik Naggum <email@example.com> Date: 03 Jan 2003 23:23:28 +0000 Newsgroups: comp.lang.lisp Message-ID: <firstname.lastname@example.org> * Jules Grosse | 1) How can I reproduce the following behaviour: | | (dotimes (x 10) | (dotimes (y 10) | (do-something-with x y))) | | Using only one "do" construct? How about only one "loop" construct? It does appear to be homework, so it may be instructive to look at what Common Lisp may look like and yet be maximally inadmissible. (prog (x y) 0 (setq x 0) 1 (setq y 0) 2 (do-something-with x y) 3 (cond ((< (incf y) 10) (go 2)) ((< (incf x) 10) (go 1)))) It is sometimes exceptionally useful to be able to build things from such basic building blocks, however. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
