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

    .global WinMain
    .extern MessageBoxA
    .extern ExitProcess

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

    .text
WinMain:
    push { lr }
    mov r3, #0
    ldr r2, =szCaption
    ldr r1, =szContent
    mov r0, #0
    bl MessageBoxA
    eor r0, r0

    pop { pc }
