用汇编语言比较三个位数的大小,如果三个数相等 输出等号,如果三个不同 按从大到小的顺序输出,急用 !!

原先写过一个类似的,你可以参考一下,

题目:1试编写一个汇编语言程序,要求从键盘接收三个16进制数,并根据对三个数的比较显示出如下信息:

(1)如果三个数都不相等则显示ALL NOT EQU;

(2)如果三个数有两个数相等则显示TWO EQU;

(3)如果三个数都相等,则显示ALL EQU。

程序:

data segment

string1 db 16 dup(?)

string2 db 16 dup(?)

string3 db 16 dup(?)

string4 db 'ALL NOT EQU'

string5 db 'TWO EQU'

string6 db 'ALL EQU'

data ends
