Are you running CSH or TCSH?  things are different between those and the
Bourne shell derivatives.. (I know nothing about Korn shells, tho...)

Anyway, I'm not a shell expert, but here are some things to do in BASH:

$ set	<--displays all variables..
$ export PATH=$PATH:/new/dir/to/add	<-- Appending an existing variable
$ export PATH=/first/dir:$PATH		<-- Prepending an existing variable
