功能：
1) 從磁盤文件中讀入一些字母(程序中只載入一屏306個字符）
2) 運行時，可按照屏幕顯示的字母輸入練習(模擬金山打字,這個實現很有挑戰性哦，先拷貝過去運行下看看效果哦)
3) 輸完結束或按ESC結束.結束時可顯示出練習輸入的時間，并顯示出正確率.
說明:
該程序主要分成（刮弧中為相應主要的函數塊）
1）打字事例文件加載模塊（LoadFile ）注：加載文件的時候提供絕地路徑，而且文件中字符不宜太少，最好多于306個。
2）打字屏幕提示及打字窗口模塊（clew_char，isFullLine ）注：這里是算法的集中點，注意提示功能和退格功能的實現，特別注意退格時候對字符統計的影響的處理。
3）打字時間及正誤統計模塊（TONGJI) 注：這里主要注意的是時間的顯示和正確率的計算，試試哦自己獨立實現下，很有趣的呢。
4）打字結果計算與顯示模塊( UseTimeAndOut，RightRata_out) 注:怎么把結果顯示在屏幕上的呢,匯編中只能輸出字符(串)呀,這里的技巧啊,先想想哦(整數123,雖然是一個數可在屏幕上輸出''1''''2''''3''可不簡單呢,還有帶小數的(如98.34)怎么輸出呀?嘿嘿想想吧,肯定是要轉換的,但這算法.....)
由于是很早前做的東西,當時又沒有做好文檔注釋,現在也沒時間重新揀起來.放在硬盤上刪了可惜,貼出來至少對剛接觸匯編又匯編感興趣的朋友還是有所幫助的.我做些大致性的標注希望能有所幫助（一般函數名表示該函數的主要實現的功能，宏也類似）.
