to dwh -listen guys, I just looked up that book. I heard of it, and had to teach others in other forums what I thought the author was using, based on what the poster posted. When I said "heard of", I only meant from some poster that was asking about the stuff in it. Now you are telling me I am talking to him? There are some things that would have to be real clear now. -Thanks fer the heads up in addressing the post.
