limiting to "no less than" zero

[Heckler]

Hey Charles... you beat me to it

When I started my reply, you had not posted yet. I am not sure I like the new code posting window... it gave me fits and I had to start over.

I think I like yours better... but it is fun and informative to try different bits of code and compile each and see how the byte count changes. I have been surprised at times in finding that what you think should be more compact code ends up being more bloated.
