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
    .extern ExitProcess

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

    .section .text
WinMain:
    sub rsp, 40

    xor ecx, ecx
    lea rdx, [rip + szContent]
    lea r8,  [rip + szCaption]
    xor r9, r9
    call MessageBoxA

    xor eax, eax
    add rsp, 40
    ret

編譯、執行

$ winegcc main.S -o main.exe
$ WINEPREFIX=~/.wine_x64 wine main.exe.so
