It appears that I made the classic mistake of assuming win95 is consistent
<g>. On my machine at home, I have no virtual memory in a DOS box. On my work
machine I do.

I make my judgement about this on the basis of Rhide. In a DOS box (at home)
and under CWSDPR0 (and CWSDPMI with virtual memory disabled), Rhide always
reports less available memory than physical memory. Under CWSDPMI with
virtual memory enabled, Rhide always reports more available memory than
physical memory.

On my work machine, this is not so for a DOS box.

I have no idea what the difference is.
