Hi,

Does any product exist that provides virtual memory under Extended-DOS?

Is it correct to say that most DOS extenders just allow access to the
RAM in the machine ("break the 640K barrier"), but don't provide
virtual memory?

We have workstation application which is multi-megabyte in size when
linked (4-6MB depending on machine). The data in memory can also be
extremely large (1-???MB depending on job). We believe it is portable
enough that it should compile using one of the 32 bit C/C++ compilers
available now (Watcom, Metaware, etc) and Extended-DOS. However, it
seems imperative that some kind of virtual memory facility be available
for this to be feasible, since PCs with 8MB of RAM seems to be regarded
as pretty well spec'd up, and that would be just enough space to load
the OS and the executable, ie, no data.

We are aware that Windows 3.0+ will solve our virtual memory problem,
but we use a home grown GUI which we don't want to replace with Windows
GUI just yet. If we can get over this problem, we have something that
runs on the PC now, and we can work on our Windows version.

Thanks,

Paul.
