这是为什么，不能输出结果也不能中断程序，只能右上角关闭

代码本身问题, debug追踪看哪儿出错。

.model small
.stack
.data
inputMsg db "Enter a string: $"
inputStr db 100, 0

.code
start:
mov ax, @data
mov ds, ax

错的都是原则和基本错误 ,用AI写代码还要侦错还不如自己写.....

程式本身的限制是:输入的数字,字母和其他字符都不能超过9个,否则错误.
修改如下.....
1.
inputStr db 100, 0
改为
inputStr db 100, 0 , 100 dup (?)
2.
mov si, offset inputStr
nextChar:
mov al, [si]
cmp al, 0
je countDone
cmp al, '0'
jb notDigit
cmp al, '9'
jbe isDigit
notDigit:
cmp al, 'a'
jb otherChar
cmp al, 'z'
jbe isLetter
上一段改为
mov si, offset inputStr + 2 ;实际输入地址
mov al, [si-1];取实际输入数
cmp al, 0;有否输入
jz exit;没有,离开
nextChar:
lodsb;取字符
cmp al,0dh;是否回车
jz countDone
cmp al, '0'
jb notDigit
cmp al, '9'
jbe isDigit
notDigit:
and al,5dh;转大写
cmp al, 'A'
jb otherChar
cmp al, 'Z'
jbe isLetter
3.
mov ah, 4Ch
int 21h
.data
crlf db 0Dh, 0Ah, '$'
digitsMsg db "Digits: $"
lettersMsg db "Letters: $"
othersMsg db "Other characters: $"
end start
改为
exit:;--加label
mov ah, 4Ch
int 21h
.data
crlf db 0Dh, 0Ah, '$'
digitsMsg db "Digits: $"
lettersMsg db 20h,"Letters: $";---加空白
othersMsg db 20h," Other characters: $";---加空白
end start
