In the October issue of Byte, there's mention of the shared program
option in Desqview windows.  What it says (and I'm working from memory) is
that if you specify a shared program, then DV will make sure a copy of that
program is loaded before the window is opened; if one is already loaded, you'll
share the same copy, rather than loading a new one.

This gave me the idea of loading some of my TSRs to be shared between different
windows - the context sensitive help TSR from Object Professional, Anarkey,
things like that.  I definitely don't want them loaded in every window, or
I'd just try loading them before running DV.

The trouble is that the shared program gets loaded by DV, not by DOS, and
doesn't get a PSP, so you have to write it in a special format.  My question
is:

Can a shared program call DOS, especially DOS's Exec service, and load a
bunch of TSRs?
