This is probably a hold-over from my formative years programming a 64KB Atari, but I try to reduce the number of variables used, if possible. This is situationally dependent, of course, and may not work in all instances. That's why I really like Alex's offering. It is elegant, minimizes conditional statements, and uses only one variable.
