这是一个学生成绩管理系统，其中“I”表示插入，“L”表示浏览，“Q”表示查询，

“E”表示退出，“D”表示删除，“M”表示修改,"c"表示统计各分数段人数,"p"表示打印.

本程序实现了：

（1）单独运行以上各功能,即在进入主菜单以后，点一功能键后关闭，再进入主菜单

点别的功能键。如运行"cjgl"文件后,在出现的主界面中点“I”，可插入数据，插入完

以后，关闭；在出现的主界面中点“M”，可修改数据，修改完以后关闭，用同样的方法

可运行其它的功能。

（2）连续运行部分的功能。



应将文件"score.txt"放在相应的路径下.如在本程序中,需将该文件放在"c:\masm\score.txt"下.



注:该文件的路径可从汇编源文件的"fname db "c:\masm\score.txt"""中查找.-This is a student performance management system, in which " I"　for insert, " L"　means that the browser, " Q"　indicates that the query, " E"　to quit, " D"　means to delete, " M"　indicates modification, " c"　indicates statistical The number of fractional section, " p"　represents Print This procedure has: (a) a separate operation of the above functions, ie after entering the main menu, tap off after a function key, and then enter the main menu to something else function keys. Such as running " cjgl"　file, in the event of the main interface midpoint " I" , the data can be inserted, insert finished, close　midpoint of the main interface appears " M" , you can modify the data, modify finished off with The same method can be run other functions. (2) continuous operation part of the function. Files should be " score.txt"　placed in the appropriate path, such as in this program, you need to p
