Foreach: Words not parenthesized. csh

Shell Programming and Scripting
1

Just started shell scripting for the first time today :smiley: Can anyone tell me why I get the error "foreach: Words not parenthesized." for my following code? The program takes in a list of arguments.

foreach card ($argv) 
        echo Hello 
end

This is lecture#1 of the "why not to use c-shell".
It expands the given arguments, and stumbles over characters that have a special meaning to the shell.
Later versions of tcsh can be made more robust by ($argv:q) or the equivalent ($*:q), but still this a hack rather than a solution.
Best is Bourne shell (and derivates like ksh, bash, zsh) with a different syntax:

#!/bin/sh
for card in "$@"
do
 echo "$card"
done

Unfortunately, I am required to make a card game using only c-shell for a class. I am well aware it sucks, otherwise I would not be asking such a basic programming question :confused: Is there any workaround in csh? Thanks
