title: Incorrect syntax parsing :setvar in SQLCMD mode
body: <p>I downloaded an AdventureWorks 2012 LT Script from CodeProject, but when I try to run it it says:</p>
  
  <blockquote>
    <p>Incorrect syntax was encountered while parsing :setvar.</p>
  </blockquote>
  
  <p>There's nothing more than this:</p>
  
  <pre><code>:setvar SqlSamplesDatabasePath   "C:\Program Files\...\DATA\";
  :setvar SqlSamplesSourceDataPath "C:\Samples\...\";
  </code></pre>
  
  <p>And yes, I set the SQLCMD mode on.</p>
