title: Does double quote makes any difference in setenv command in Linux csh?
body: <p>I am setting an environment variable - say ABC -  in C shell in SuSe Linux.</p>
  
  <p>My question, are there any difference in following 2 commands?</p>
  
  <ol>
  <li><code>$setenv ABC "1"</code></li>
  <li><code>$setenv ABC 1</code></li>
  </ol>
  
  <p>In both the cases <code>echo</code> gave me the same result.</p>
  
  <p>i.e</p>
  
  <pre><code>$echo $ABC 
  1
  </code></pre>
  
  <p>For me, it looks to be both are same. But I wanted a confirmation to proceed.</p>
