BASIC程序求助
我准备做一个灰色系统的GM(1,N)程序.找到一个用GWBASIC的,但是运行错误,求高手帮忙修改一下!!!谢谢!!!!!源程序如下:10REM****************************************************

5000 CHAIN "SJWJ2" 有高手帮忙改成VB或者其它语言的更好 天哪……GWBASIC……好亲切，仿佛回到了十年前…… 能不能帮忙检查一下,2090行提示XX(I,J)下标越界
5000 CHAIN "SJWJ2"是联结的一个文件程序 原帖由 ppjj 于 2007-6-14 12:51 发表 http://www.chinavib.com/forum/images/common/back.gif
