不知道那错了？？？？？？

[LunTanZeng]

我帮你顶！！！

[kenko]

将错误信息帖出来看看

[hcj2002]

没有错误信息！

但出不了正常结果

等待中……

[紫郢剑侠]

没有定义堆栈段却有堆栈操作?

[紫郢剑侠]

CRLF proc near ；输出回车换行
mov ah,02h
mov dl,0ah
int 21h
mov ah,02h
mov dl,0dh
int 21h

;=========================
ret ;楼主漏了这句, 程序将引起死机:-<
;==========================
CRLF endp

另外程序的逻辑好象有点问题...
