csh and echo

I'm writing a script within which I need to have encrypted passwords 
passed to 'pw mod user'.  My issue is that csh does not seem to escape 
the the "$" correctly and thus I receive an "Undefined variable" error 
message.  Bash does not seem to have this same issue:

root@fbsdtest13:~ # echo "$1$rVxldcGZ$CisrIAX4SBYUkMJt9KjXl0"
rVxldcGZ: Undefined variable.
root@fbsdtest13:~ # bash
[root@fbsdtest13 ~]# echo "$1$rVxldcGZ$CisrIAX4SBYUkMJt9KjXl0"

[root@fbsdtest13 ~]# echo "\$1\$rVxldcGZ\$CisrIAX4SBYUkMJt9KjXl0"
$1$rVxldcGZ$CisrIAX4SBYUkMJt9KjXl0
[root@fbsdtest13 ~]# exit
root@fbsdtest13:~ # echo "\$1\$rVxldcGZ\$CisrIAX4SBYUkMJt9KjXl0"
rVxldcGZ: Undefined variable.

Any insight would be greatly appreciated! :)
