【Ubuntu】7.10光碟開始提供索取申請
這幾天讓人很興奮的是Ubuntu 7.10終於要釋出了！今天已經進入倒數九天了，從倒數十一天起就一直跑去Ubuntu官網晃，關注了兩天終於開放申請索取7.10的光碟，身為Ubuntu的忠實愛好者，當然也要趕緊來參一腳。這次申請選項少了一點，預設的光碟索取組合變得比較『不浪費』，這次預設選項最多2張光碟片，可以選擇兩張PC版的或是選擇PC、64bit版各一張。
有興趣的使用者也可已到https://shipit.ubuntu.com/申請，如果需要地址翻譯的話可以參考台灣郵政網頁提供的轉換服務

【X86組語】大小寫轉換
題目說明：
等待使用者輸入字母（'a'～'z'與'A'～'Z'），並做大小寫轉換。如果使用者輸入小寫字母，則螢幕印出對應的大寫字母，反之印出對應小寫字母，若輸入字母以外的字元則結束程式。
程式流程：
程式碼：
