2.51单片机为基础用汇编语言编写用数码管显示一个同时有"加""减""乘""除"法功能的源码淘宝红包通道源码计算器程序，急用参考

我原来的源码libatlas 源码写法：用subb
MOV a,h
CLR c
SUBB a,h
JZ YES //a为0跳到YES
MOV h,#h //不相同
JMP OVER
YES:
MOV h,#h //相同
OVER:
///////////////////////================
上面这位兄台用CJNE是不是忘了加个jmp over
MOV A,H
CJNE A,H,MARK
JMP OVER //对上所改
MOV H,#H
MARK:
MOV H,#H
OVER： //对上所改
否则不管如何都会执行 在h里存0了
