title: "The syntax of the command is incorrect" error when printing a pipe
body: <p>I am trying to write a batch script that simulates a progress bar, using <code>|</code> characters to show progression.</p>
  
  <p>Unfortunately, whenever I try to show the progress bar, I get the error "The syntax of the command is incorrect." What am I doing wrong?</p>
  
  <p>My code:</p>
  
  <pre><code>@echo off
  color 0F
  mode con: cols=51 lines=18
  cls
  echo                   _____________
  echo.                  |
  echo                   _____________
  </code></pre>
