While loop in tcsh

Hi,

I was trying to code a simple while loop in tcsh shell.

#!/bin/tcsh
set cnt=5
while ($cnt > 0)
cnt = $cnt(`expr($cnt - 1))
end

However I am getting the following error :
cnt=4: command not found (Error is going on till <ctrl+c> is pressed.

Is this an error with the syntax?

Thanks
