Oh, you can have more fun than that.  I use rlogin for concurrent logins
on up to three machines from my home machine.  So I don't get too
confused, I want the machine name and path displayed all the time.
I also use the csh history functions, so I want the history number
displayed with each prompt.  SO:

setenv HOST `hostname`
set prompt="$HOST(\!): <to stat>$cwd<back from stat>"
alias cd  'chdir \!* ; set prompt="$HOST(\!): <to stat>$cwd<back from stat>"'
alias pd  'pushd \!* ; set prompt="$HOST(\!): <to stat>$cwd<back from stat>"'
alias po  'popd  \!* ; set prompt="$HOST(\!): <to stat>$cwd<back from stat>"'

The <to stat> is the escape sequence necc to start writing in the
status line, and the <back from stat> returns to the current line.
Note: If you only have one machine, you only need to print out the
stat line when you chdir, pushd or popd.  But popping back and forth
between three background rlogins and my home machine, whenever I get
a new prompt, voila.

It takes a little longer to cd, but it was fun while my prompt slowly
developed.  Now I'm on a wyse75; the bottom status line runs a niced
sysline, while the top status line has my current working directory.

Happy hacking!
