提示用户输入考试成绩（1-100），要求输出该分数和相应等级。
分数等级如下：
分数 等级
79-100 A
67-78 B
54-66 C
40-53 D
〈40 E
我的程序是：
input "testpoint(1-100)";n
select case n
case 79 to 100
m$ = "A"
case 67 to 78
m$ = "B"
case 54 to 66
m$ = "C"
case 40 to 53
m$ = "D"
case 0 to 39
m$ = "E"
end select
print n
print m$
如果我想限制他只能输入0-100，又该加什么代码？？？

命令有作用就用，不存在流行不流行的问题。
