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

    %include "c:\\nasmx\\inc\\nasmx.inc"
    %include "c:\\nasmx\\inc\\win32\\windows.inc"
    %include "c:\\nasmx\\inc\\win32\\user32.inc"
    %include "c:\\nasmx\\inc\\win32\\kernel32.inc"

    entry start

    section .data
szCaption declare(NASMX_TCHAR) NASMX_TEXT("main"),0
szContent declare(NASMX_TCHAR) NASMX_TEXT("Hello, world!"),0

    section .text
proc start, dword argc, dword argv
    locals none

    invoke MessageBox, NULL, szContent, szCaption, MB_OK
    invoke ExitProcess, NULL
endproc

Line 1~4：Header檔案
Line 6：程式進入點
Line 8：初始化的資料區段
Line 9~10：初始化的Global變數，型態是TCHAR且最後一個byte是0
Line 12：程式區段
Line 13~18：proc、endproc用來定義Procedure的區間
Line 14：沒有Local變數
Line 16：顯示Message對話盒
Line 17：結束Process並且釋放相關資源

Makefile

export WINEPREFIX=/home/user/.wine_x86
