More or less, you must put both in the same window and cross commands to
scroll both at the same time (to compare the text).

DJGPP is 10 years old. I talk about time during the next months, not this
week or the next ;-)

:-)), I think that the harder part is knowing about Turbo Vision, C++ is
easy.

I include a script (sacadeb.bat) to cut the debug info. That's in the readme
;-)
My numbers are *without* debug information, otherwise it climbs to about
1.2Mb ;-))).

Almost impossible, to cut all, the TApplication/TProgram classes does
explicit calls to TMenu members and hence you'll get it linked.

That's impossible, no TVision application ca really work without it. You
could write some replacement for TProgram and work with it, but: did you see
my numbers? you'll gain 10 or 20 Kb in a 220Kb program.

Nope, the menubar is a memeber of TProgram you need to go even deeper and
create a new thing from TView. I think it isn't a really good idea.
