得到这段代码纯属偶然。开始我也不相信是微软的，但是我读了程序，发现还真是微软的东东，不过是DOS 4.0的。具体的来源，我也不太清楚。难道是哪位高人从微软偷来的？呵呵，不管那么多了。先来研究研究再说！ -Get the code by accident. I did not believe Microsoft, but I read the program, found that Microsoft' s stuff really is, but DOS 4.0' s. Specific source, I' m not sure. Which is it stolen by an expert from Microsoft? Oh, do not Guannameduo. First to study the research to say!
