A professor in college took points off one of my programs because I didn't test for 0 first. He explained that testing for either negative or positive first left you vulnerable on 1's-complement machines, where comparisons for <0 or >0 just checked the sign bit, and either form of 1's-comp 0 would pass one of those tests. I looked at him like he was insane. He looked at me the same way. He was old enough that I suppose he's dead now. Ha! I win <wink>. elif-is-file-spelled-backwards-ly y'rs - tim
