If the >variable "side" is for instance of type "short", the compiler has to zero-extend >the variable to word-size before indexing (because of the array access). But as you can see the variables are all ints. So no type conversions needed. I believe there is just some stupid alignment thing happening or something and that's why the program slows down a bit. I'd use side instead of color(sq) and hopefully the speedup will show up later. Severi
