OK, Marshall, I'm not understanding your logic here at all. Could you be specific about what you are trying to prove? I suspect that I agree with what you are trying to prove. However, it is not the case that navigation implies iteration, which was my point. They are sepraate concepts even if often seen in each others company. I suspect we agree on both points so I'm not sure what the game is. --dawn Received on Sat Feb 17 2007 - 10:32:19 CST
