Hi Barry, I have a lot to learn, no doubt. I usually just run a B&B and
thrash my car with a tree limb when I get upset... this programming is tough
stuff, but I'm learning, slowly. My hat is off to all who do this for a
living, that and those who help, give advise and recommendations to tards
like me out here no one has to do it but they did. It really does help me
learn and get a grasp on the language, even if what I'm doing is childs play
to most of you, it does hep me in other areas of my work life. Again, many
thanks! --Basil
