Thanks to all you guys for your recent help getting me "jump-started" with Assembly. Now, I have another question, just for curiousity. I've heard it said that writting in Assembly brings speed with it. Rick was talking about re-writting repetive FNs in Assembly for speed, and I've heard about game programmers that write some sections in Assembly for shear speed. Now, here comes the question: If all code (C, Pascal, FB, any language like that) is compiled into a CODE resource when it's app is built, why is there a speed increase when writting in Assembly? Now, I understand inserting assembly in an INTERPRETED languages (Applescript, Usertalk, Hypertalk, C64 Basic, AppleII Basic, etc) would DEFINANTLY show an increase in speed, but why does it make ANY differance at all in COMPILED languages? Is it because humans can write tigher assembly code then current computers can, resulting in less instructions, and a shorter execution time (I don't know here, just guessing :) )? Or, is all of this "Assembly = Speed" issue just a myth? Questioning again :), -Wilcox [-)
