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:
    stp x29, x30, [sp, #-0x10]!
 
    mov x0, 0
    ldr x1, =szContent
    ldr x2, =szCaption
    mov x3, 0
    bl MessageBoxA

    mov x0, 0
    bl ExitProcess
 
    mov x0, 0
    ldp x29, x30, [sp], #0x10
    ret

Line 1：程式進入點
Line 2~3：external function
Line 5：初始化的資料區段
Line 6~7：初始化的Global變數，型態是byte(char)且最後一個byte是0
Line 13~17：顯示Message對話盒
Line 19~20：結束Process並且釋放相關資源

編譯、執行
