No. This is a reasonable question, but you need to understand something about DOS: it's not really an operating system. It's a file system and program loader. When you call DOS from some program it loads COMMAND.COM and passes control to it... completely. The previously loaded program is hidden. Think of it as a stack: you push a program on top of the stack, and pop one off. There are operating systems you can buy that load under DOS and provide an interface to it: DesqView, Windows, DoubleDOS, etc... perhaps one of those will let you do what you want. Or you could switch to a computer with a real operating system, but I suspect that's not an option. -- Peter da Silva. `-_-' peter@ferranti.com +1 713 274 5180. 'U` "Have you hugged your wolf today?"
