>>>Hi George - Let me use Jim's PI example...does it really matter whether you use a local or a #define for the PI value? I've always used locals or properties for such things, but am wondering if it's worth moving to constants.

Probably the performance difference is not great, since there are a limited number of cases when one uses locals that one doesn't need to change the value. And they kind of give a more "cluttered" look to the code. So I'm in conflict about it right now :)

It's a convention that constants be entered in all uppercase, but not necessary. You can use mixed or lower case if you want. That may help with the cluttered look.
