Just to illustrate exactly how sick I am, this took about three hours, most of which was fidgeting with the editor to make the geometry work. OK, I cheated a bit by: -- putting the text in the program -- using the fact that functions with an empty stack are essentially nops And I didn't use anything nifty--no multithreading, genuine conditionals, or anything of the like. Just brute force. I did, however, when I was running out of space, "put" the coordinates in memory so I could just "get" them later. Anyway, I found at least one not-quite-as-advertised "feature" in the interpreter. The main one is that a zero on top of the stack does a put of put and get, instead of the expected get, and a non-zero does get instead of put. Since I was doing more getting than putting in the program, I was actually kind of happy, but that means the spec and my comments are wrong (unless you *really* want to declare the least-trivial piece of Wierd code written to date *and* the only currently implemented interpreter non-standard...). The others are really obscure things that I can't figure out how to fix (the gap-jumping doesn't seem to quite work as I understand it). Well, I could probably strip out another couple of bytes here and there, but I just don't have the stomach for it today... Oh, Ben: If you're going to try a 99-Bottles program, I'd suggest expanding the playing field, since this program clocked in at just under 128x128... Now I'm going to bang my head against a softer object for a while so I don't notice the pain... --John P.S. Anybody besides me see the portrait of George Washington in the program? No? I must be hallucinating, then...Oh, well...
