GNU screen

Hello,

One of the things I like about screen is that it has a scrollback buffer, which if you go into the copy mode, will let you go back for a specified number of line. Is there a way to extend the number of scrollback lines in screen? I've looked thoroughly online and I could not find a solution short of going to the source code of screen and tweaking it.

Thanks,
Neked

NAME
clear - clear the terminal screen SYNOPSIS
clear [-Ttype] [-V] [-x] DESCRIPTION
clear clears your screen if this is possible, including its scrollback buffer (if the extended "E3" capability is defined). clear looks in the environment for the terminal type given by the environment variable TERM, and then in the terminfo database to determine how to clear the screen. clear writes to the standard output. You can redirect the standard output to a file (which prevents clear from actually clearing the screen), and later cat the file to the screen, clearing it at that point. OPTIONS
-T type indicates the type of terminal. Normally this option is unnecessary, because the default is taken from the environment variable TERM. If -T is specified, then the shell variables LINES and COLUMNS will also be ignored. -V reports the version of ncurses which was used in this program, and exits. The options are as follows: -x do not attempt to clear the terminal's scrollback buffer using the extended "E3" capability. HISTORY
A clear command appeared in 2.79BSD dated February 24, 1979. Later that was provided in Unix 8th edition (1985). AT&T adapted a different BSD program (tset) to make a new command (tput), and used this to replace the clear command with a shell script which calls tput clear, e.g., /usr/bin/tput ${1:+-T$1} clear 2> /dev/null exit In 1989, when Keith Bostic revised the BSD tput command to make it similar to the AT&T tput, he added a shell script for the clear command: exec tput clear The remainder of the script in each case is a copyright notice. The ncurses clear command began in 1995 by adapting the original BSD clear command (with terminfo, of course). The E3 extension came later: o In June 1999, xterm provided an extension to the standard control sequence for clearing the screen. Rather than clearing just the vis- ible part of the screen using printf '33[2J' one could clear the scrollback using printf '33[3J' This is documented in XTerm Control Sequences as a feature originating with xterm. o A few other terminal developers adopted the feature, e.g., PuTTY in 2006. o In April 2011, a Red Hat developer submitted a patch to the Linux kernel, modifying its console driver to do the same thing. The Linux change, part of the 3.0 release, did not mention xterm, although it was cited in the Red Hat bug report (#683733) which led to the change. o Again, a few other terminal developers adopted the feature. But the next relevant step was a change to the clear program in 2013 to incorporate this extension. o In 2013, the E3 extension was overlooked in tput with the "clear" parameter. That was addressed in 2016 by reorganizing tput to share its logic with clear and tset. PORTABILITY
Neither IEEE Std 1003.1/The Open Group Base Specifications Issue 7 (POSIX.1-2008) nor X/Open Curses Issue 7 documents tset or reset. The latter documents tput, which could be used to replace this utility either via a shell script or by an alias (such as a symbolic link) to run tput as clear. SEE ALSO
tput(1), terminfo(5) This describes ncurses version 6.1 (patch 20180127). clear(1)
