When I start COMMAND.COM running from Epsilon, it does *not* run in a 
window.  It goes off and does its thing, and when you exit from COMMAND.COM
and whatever compilers you are running, you are back in a window, but
it doesn't operate in anywhere near the manner that EMACS does under UNIX,
which the press releases I have seen strongly suggest.  This is what I
mean.
