title: Exit tcsh script if error
body: <p>I am tryin to write a tcsh script. 
  I need the script exit if any of its commands fails. </p>
  
  <p>In shell I use <code>set -e</code> but I don't know its equivalent in tcsh</p>
  
  <pre><code>#!/usr/bin/env tcsh
  
  set NAME=aaaa
  set VERSION=6.1
  
  #set -e equivalent
  #do somthing
  </code></pre>
  
  <p>Thanks </p>
