I could tell you what they mean but then I'd have to kill you. :-) It definitely is not a good idea to try to use them for something completely different. It seems better to just add a (...)

Having made an earlier suggestion about using file names to extend the capabilities, I've looked into it a little further and found something very useful. The 'NXTDrawPicture', or 'DrawGraphic' command can take an arbitrary array of variables. The (...) (18 years ago, 21-Feb-07, to lugnet.robotics.nxt)
