經典的Hello, world!程式框架總是能夠讓人細心品味一款程式語言的美好，司徒就使用一個簡單的Message對話盒來展現Hello, world!框架

main.asm

    [bits 32]
    global _start

    extern _MessageBoxA@16
    extern _ExitProcess@4

    %define MessageBox  _MessageBoxA@16
    %define ExitProcess _ExitProcess@4

    section .drectve info
_entry    db "/entry:start "
_gdi32    db "/defaultlib:c:\\masm32\\lib\\gdi32.lib "
_user32   db "/defaultlib:c:\\masm32\\lib\\user32.lib "
_kernel32 db "/defaultlib:c:\\masm32\\lib\\kernel32.lib "

    segment .data
szCaption db "main",0
szContent db "Hello, world",0

    segment .text
_start:
    push 0
    push szCaption
    push szContent
    push 0
    call MessageBox

    push 0
    call ExitProcess

Line 1：32位元模式

Line 10~14：傳遞給Linker的指令
Line 16：初始化的資料區段
Line 17~18：初始化的Global變數，型態是byte(char)且最後一個byte是0
Line 20：程式區段
Line 21：程式進入點
Line 22~26：顯示Message對話盒
Line 28~29：結束Process並且釋放相關資源
