Say you have a loop that increments a counter variable and you only want the counter value to loop back around similar to your hi/low example. A neat trick is to use the modulus operator so if you want to use just degrees for a circle for example you would just do: (ctr % 360) + 1 Or if you only want 1 - 100 to show just do (ctr % 100) + 1 and this will guarantee that you only have to deal with numbers 1 through 100.
