Well, you've convinced me of everything except the theoretical inelegance. I still think this optimization demotes procedures to second-class status, but I can live with second-class procedures. -- John Cowan http://www.ccil.org/~cowan co...@ccil.org "After all, would you consider a man without honor wealthy, even if his Dinar laid end to end would reach from here to the Temple of Toplat?"
