Oh, but wait. NEWSUD is such a minor change... in perspective ... that it's probably not that big a deal. The hard part will, I think, be doing it in a way that's really efficient. You don't want to introduce if blocks in every computation, and you surely wouldn't want to call a function for every direction. Probably an array of dirs qw(n e s w) and qw(l r u d) ... requires some thought.
