Yes, win95 allows at most 64Mb of DPMI memory. cwsdpmi allows 128.

You can setup DPMI memory in the "memory" tab in the dos box properties.
Don't use "auto" because it is not sufficient. Put 65535

>(can I allocate 40MB of memory under win95 dos box ?,   under CWSDPMI ???)
Yes and No. win95 doesn't allow to alloc more than half the remaining space
at once, so you can't malloc 40Mb but you can malloc 20 + 20 Mb.
cwsdpmi has'n got this problem IIRC.

>P.S.  I prefer DOS, but it doesn't support long file names :(((

You can have a look at Caldera DR OpenDos, it provides some multitasking
and
some lfn handling. I haven't lookad at caldera's site (www.caldera.com/dos)
for some time, so I don't know exactly at what stage the compatibility with
win95 lnf is, though.
And also, it was free for personal use once, but I don't know now it still
is.
