(actually, in that case, i guess it would be a question of how much longer than ksh zsh takes to load; i know zsh is much larger, but if it is loading dynamically, it shouldn't take that long to start up, right?) expanding parameters, sweth. -- "Countin' on a remedy I've counted on before Goin' with a cure that's never failed me What you call the disease I call the remedy" -- The Mighty Mighty Bosstones
