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.S

    .intel_syntax noprefix

    .global WinMain
    .extern MessageBoxA

    .section .data
szCaption: .asciz ""
szContent: .asciz "Hello, world!"

    .section .text
WinMain:
    push ebp
    mov ebp, esp

    push 0
    push offset szCaption
    push offset szContent
    push 0
    call MessageBoxA
    add esp, 16

    xor eax, eax
    leave
    ret
