- [游客] mov bx,100(64h),好像书也是错的 04/16 19:55
- [游客] 在debug 里是默认十六进的，在源程序是默认10进制的，加多一个h就、行 04/16 19:52
- [ghosteye] 这样子应该可以 inc cx 或者 mov cx,1 04/16 15:30
- [ghosteye] 没有错，我还没有注意看，你够仔细的 04/16 15:26
- [billy_asm] 如果inc bx 能在jcxz ok之前,应该没有问题的. 题目却相反. 04/16 15:13
- [billy_asm] 对不起,上一次我也没看清ok标号后的dec bx 如果没有它,jcxz ok是没有问题的. 因为 04/16 15:11
