I think you mean CMD. It is similar to the MS-DOS style command prompt found in Windows 9x.
If you type a command followed by /? then you get a list of possible arguments. Dir /p lists all your files in a certain directory, whilst pausing at each screenful so you can read it.
With some commands, such as HELP, if you type:
HELP | More
then it does the same as /p for the DIR Command.
Not much more you can do in XP with the CMD console. If you really want to mess around with a proper command line, then install MS-DOS 6.22!
