In csh, it's "foreach", like this (tested):

foreach luser (joe peter bill)
   echo $luser
end

The csh man page says: "Both foreach and end must appear alone on 
separate lines."

But you should not use csh for scripting[1].  Instead, stick to standard 
sh (tested):

for luser in joe bill ted; do echo $luser; done

But that's ugly.  Unless there's a good reason to stick with shell 
scripts, consider using Perl or Python[2] from the start.

[1] Google for it.
[2] I'd lean towards Python currently.  Shame about the string
     interpolation, though.
