Bash supports 4 prompts:

PS1 - the default prompt
PS2 - for multi-line input
PS3 - printed for the select command
PS4 - printed before output if set -x is set

(see http:// www . gnu . org/software/bash/manual/bashref . html )
The first two are common to the Bourne shell (and ksh). The last two are only for Bash.

csh, however, uses a completely different system. Set the "prompt" variable.
