Oh, one more thing. I am pretty sure that the program is written in Borland Turbo Pascal, in case that rings any bells about peculiarities with dealing with the operating system. This version is Cadd6.0, released just after their acquisition by the (bleep) Autodesk, and was the last useful version. I think it came out about 1987. --jim - To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
