I would prefer the Windows version, but I only was able to write the DOS
version. And of course it's nice not only to have a OpenCD() routine,
but also a CloseCD() routine.

I've got a question: When a computer has 2 or more CD drives, how do
your procedures "know", which drive they should open/close?

Thanks and best regards,
