Subject: Re: Help with a program to determin leap years.

AH! i was looking at it wrong...startin from validating divisible by 4
is the wrong direction...thank you all. I think I can make it work now
(many of you posted rather more advanced ways to do it. I am trying to
stick within the confines of the chapters ive done so far). Basically
I needed the way to approach the problem. Thanks all!
