Gee, that sounds interesting.  Don't try it unless you know more about
this stuff than it sounds like you do.

In SALAD (Still Another Line-A Document) the negative line-A variables
are documented, and among them you will find a "number of vertical
alpha cells" variable (better known as "number of text lines").  Set
this smaller than it already is, and you will have created a short
screen with unused lines at the bottom -- lines you can use for your
status stuff.  Of course, you can't use Bconout to write to that status
area... Unless you write in the true value for "number of lines," then
go to the bottom and write what you want, then write in your fake
"number of lines" value.

SALAD is available to developers in a couple of places, including
online on GEnie and possibly other services.  Or call Gail Johnson,
(408) 745-2000, to get it (or become a developer if you aren't one
already).
