MASM32
Hello, world!

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

invoke ExitProcess, 0
end start
Line 1：CPU指令
Line 2：記憶體類型是flat，calling convention使用stdcall
Line 3：程式區分大小寫
Line 5~7：Header檔案
Line 9~10：Library檔案
Line 12：初始化的資料區段
Line 13~14：初始化的Global變數，型態是byte(char)且最後一個byte是0
Line 16：程式區段
Line 17：程式進入點
Line 18：顯示Message對話盒，invoke是一個偽指令，最終會展開成call + push的綜合指令
Line 19：結束Process並且釋放相關資源
Line 20：檔案結尾，end指令後的程式將不會被編譯
