There is a microsoft update of dosswap.exe, used with dosshell, that
is supposed to fix a few bugs. If is available at Simtel. I expect I
can find dosshell somewhere, since I have seen utility packages around
with programs in dos 5 that were not included with dos 6 and 6.22.

However, dosshell's docs say it needs a minimum of 350K conventional
memory.  Does dos shell remain in conventional memory while it swaps
applications in and out of memory?

Do you know how dosshell swaps programs in and out of memory?
I expect it puts the non-used program on hard disk. Can one define
the disk to be a ramdisk, and thus swap it to XMS memory?

One would hope a task switcher will either load high, itself, or
switch itself and the last application out of memory to make room for
the current application. Optimally, one wants as much of the 640K of
conventional memory as possible available for the current application.
conventional memory as possible available for the current application.
