There have been comments about terminfo entries for terminal mode in GNU
emacs.  Terminal mode sets the enviroment variable TERMCAP each time it
is invoked.  The number of lines and columns are set based on the window
size.  This trick doesn't work on Sys V because "termcap" entries are
compiled into the terminfo database; TERMCAP is ignored.  However,
there is an out: the environment variables LINES and COLUMNS override
the terminfo values for the TERM in use.  So, here is the terminfo entry
(courtesy of captoinfo)

emacs-virtual,
	xon,
	cols#78, lines#22,
	bel=^P^G, clear=^P\f, cr=^P^A, cub1=^P^B, cud1=\n,
	cup=^P=%p1%'\s'%+%c%p2%'\s'%+%c, dch=^Pd%p1%'\s'%+%c,
	dch1=^Pd!, dl=^P^K%p1%'\s'%+%c, dl1=^P^K!, ed=^PC,
	el=^Pc, ich=^P_%p1%'\s'%+%c, ich1=^P_!,
	il=^P^O%p1%'\s'%+%c, il1=^P^O!, ind=\n, nel=\n,

Tic this definition.  Don't change the name "emacs-virtual" unless you
also change the name in terminal.el.  

Change terminal.el so that it emits the appropriate magic to set LINES
and COLUMNS (sorry - I haven't gotten to that part of job yet - my lisp
is non-existant....). 

-----
I have noticed that not all programs that use curses will run: they
object to missing capabilities.  I have not yet determined which
capabilities are missing.  If anyone has any suggestions (and
enhancements to terminal mode), please respond.

Thanks
