I'm very sorry, I should have stated that you where completely excluded from this final comment (since I had mentioned you by name earlier in the post). I found your arguments to be excellent with absolutely no hints of anything mystical. It was some other members who made statements like this including one that actually said "mathematical manipulation is just card tricks". Again, sorry for unintentionally implying that you where in that group. Paul -- http://www.piclist.com#nomail Going offline?
