功能：
1) 从磁盘文件中读入一些字母(程序中只载入一屏306个字符）
2) 运行时，可按照屏幕显示的字母输入练习(模拟金山打字,这个实现很有挑战性哦，先拷贝过去运行下看看效果哦)
3) 输完结束或按ESC结束.结束时可显示出练习输入的时间，并显示出正确率.
说明:
该程序主要分成（刮弧中为相应主要的函数块）
1）打字事例文件加载模块（LoadFile ）注：加载文件的时候提供绝地路径，而且文件中字符不宜太少，最好多于306个。
2）打字屏幕提示及打字窗口模块（clew_char，isFullLine ）注：这里是算法的集中点，注意提示功能和退格功能的实现，特别注意退格时候对字符统计的影响的处理。
3）打字时间及正误统计模块（TONGJI) 注：这里主要注意的是时间的显示和正确率的计算，试试哦自己独立实现下，很有趣的呢。
4）打字结果计算与显示模块( UseTimeAndOut，RightRata_out) 注:怎么把结果显示在屏幕上的呢,汇编中只能输出字符(串)呀,这里的技巧啊,先想想哦(整数123,虽然是一个数可在屏幕上输出''1''''2''''3''可不简单呢,还有带小数的(如98.34)怎么输出呀?嘿嘿想想吧,肯定是要转换的,但这算法.....)
由于是很早前做的东西,当时又没有做好文档注释,现在也没时间重新拣起来.放在硬盘上删了可惜,贴出来至少对刚接触汇编又汇编感兴趣的朋友还是有所帮助的.我做些大致性的标注希望能有所帮助（一般函数名表示该函数的主要实现的功能，宏也类似）.
