A minor problem with 'curse': When it cannot find an ll entry for your
terminal, it blindly assumes you have a 24 line one. However, it could
get good information about the size of the screen by simply looking at
LINES and COLS. So, the shell archive at the end of this message
provides the fixes both to the program and the man page. I have added
two options, so you can query the number of lines/columns (and may be set
shell variables).

DESCRIPTION:
'curse' doesn't use the current size of the window
when the -ll option cannot find a 'quick to last line' entry in the
termcap.
REPEAT-BY:
If you have a terminal which is NOT 24 lines tall and
whose termcap entry doesn't contain the 'll' option, run:
curse -ll
You'll end up some weird place (column 0, line 23).
FIX-BY:
Use LINES and COLS, as defined by 'curses', in order
to figure out your screen's size. This allows for two easy options
to get the numbers of lines and columns of your terminal, say in
shell variables:
lines=`curse -li`
or
set lines=`curse -li`
diff.{c,1} are ed(1) scripts for curse.c and curse.1 respectively.
The two new options are -li and -co.

type variables are included. In addition, two numeric options
(-li and -co) are recognized, so you can adapt your work to any
screen shape size.
