now suddenly comming back to this I feel slightly suprised
You are teaching me how to code in ASM?!

Why don't you try writing an OS in C? Have you compared a C porgrams size and speed to the same program written in ASM? Size doesn't matter that much anymore though it generally is a little smaller, and speed.. Lol! You can't even compare the speed, asm is hecka faster than anything already out there.

So it's not portable, that's about the only disadvantage along with annoying coding

btw, if anyone wants the source code of JJ2 in assembly, they can IM me on AIM @ SN: Kesshutsu


Here's a better example of the hellow world program in Win32 ASM this time



.386 ; 32-Bit when .386 appears before .MODEL
.MODEL FLAT , STDCALL

include windows.inc
include user32.inc
include kernel32.inc
include gdi32.inc
includelib user32.lib
includelib kernel32.lib

.data
ClassName db "SimpleWinClass",0
AppName db "Hello!",0
TestString db "Hello World",0

.data?
hInstance HINSTANCE ?
CommandLine LPSTR ?
hwnd HWND ?
