title: Windows echo command can't echo a user-set variable
body: <p>What did I do to screw up my CMD shell?  Windows XP Pro, open a cmd window and do:</p>
  
  <pre><code>C:\&gt;set tt = name
  
  C:\&gt;set tt
  tt = name
  
  C:\&gt;echo %tt%
  %tt%
  
  C:\&gt;echo %time%
  14:13:28.67
  </code></pre>
  
  <p>The echo command doesn't work for some reason.  I can echo the built-in variables just fine.  Tried it on another computer and that works as expected</p>
