I should have clarified this: I also have an alias:

	alias -x exdos=". /mks/sh/exdos.ksh"

So when I enter:

	% exdos

I am *intending* to replaced my top-level shell with command.com.  This
*worked* on the previous version.  This is screwed up, I know, but there
used to be a *reason* for all this fooling around. . .

I have: export SHELL=/mks/bin/sh.exe

Yes, but I want to use exec to replace sh.exe with command.com.

My intent is to replace sh.exe with command.com since even with the new
transient shell I can squeeze out a bit more RAM.  Maybe that's no
longer useful, or the transient shell breaks exec.  

Let's try to simplify this: should this work from the top level shell in
config.  5? It hangs for me now:

	% exec command.com

Oh, those damned features. . .at least make them switch-settable?
