王爽老师《汇编语言》第八章实验题

stackseg segment

这是我参考答案后写出的代码,但是在运行时,若cx为12以内的数可以运行,但是如果cx大于等于12代码就会陷入死循环,不知为啥
{:10_266:}
求求各位帮忙找一下问题所在 找到问题了,来个自我解答吧{:10_266:}
最后一个为字节型数据,必须+2+2移动
因此引进SIl来指向最后一种数据
新的代码如下:
assume cs:codeseg,ds:dataseg,ss:stackseg
stackseg segment
dw 0,0,0,0,0,0,0,0
stackseg ends
dataseg segment
