Maybe it is a silly question, but if there is a push onto the stack, how the numbers are pop'ed back? Since SCO seems to be similar to ASM (I have not yet took a look to scripts, only to this article) I think it is worth to mention this in the article (if there is an awnser, what I hope ^^). --Aschratt 20:17, 5 February 2009 (UTC)

Difference Between 'Local' variables and 'Global' variables
Does anyone know it? The only difference I could possibly see between them is a public declaration in the script so other scripts could access it... I don't see how local variables are even used when function locals are supported.
