You can't really do this on a PC because you need a large virtual machine. Think about it...you need enough address space to hold all the files you have open. You could possibly do it on an AT where a big virtual machine can be implemented using the memory management hardware. It is easy on a 386. But on a PC..no page faulting and a 20 bit address...no way! -- Bob Eager rde@ukc.UUCP rde@ukc ...!mcvax!ukc!rde Phone: +44 227 66822 ext 7589
