#106143 - Swapping 2 variables without a temp.
Found this on the web and thought it might be good for the For the "wow that's a cool idea file"

For swapping 2 variables with no temporary variable, no doubt just as easy to implement in asm once you have thought of the idea.

one ^= two;
two ^= one;
one ^= two;


due credit to whoever wrote it
