Thanks for your reply. Oh, I have the screen -- it's just quite useless
for *doing* anything about the info it shows you. Maybe this is a
concrete example of one superiority to Xy-3. I could chuck stuff
overboard, if there was a need to lighten the mem. load. Sounds like
putting this in U2 would gain very little, in terms of utility.

And it's something that can't be finessed with a U2 frame either,
apparently.

And that sounds as though making some more mem. available to Editor
won't provide a cure. I could be wrong, but I don't recall that .KBD
loading problem being present in Xy-3.

Thanks for those. I'll compare this list to mine. (Haven't messed with
DOS session values in quite some time. I even forget whether it has to
be system wide for DOS sessions, or can be limited to a particular DOS
program.)
