Command
Line Buffer
The command line buffer is
part of RAM, Random Access memory, which holds the last command entered from
the DOS command line. If DOSKEY is loaded it can hold more than one command.
To load DOSKEY type the following
command:
If you wish DOSKEY to
automatically be loaded when you start your computer you can enter the command
into your AUTOEXEC.BAT with a straight ASCII editor. Just put it on the last
blank line.
The command line buffer is
different than the active command line. The active command line, also know
as the command line or DOS system prompt, displays information as it is entered.
When you type a command and press the enter key the command is then stored
in the command line buffer.

function keys you can use in conjunction with DOSKEY or the command line
