Precisely. I didn't say as such in my comments, but I understand what you are saying. Very early in my "training" this principal was drummed into my head. Actually, it's a pretty sensible assumption to make, even if it might not be correct in the absolute sense of the word. (It's MOSTLY right!) ;-) Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks
