title: Using variables in .bat files
body: <p>I'd like to use a variable in a batch file. However, when I use <code>TEST_TIME_IN_SECONDS</code> in the command below I get an error. Replacing <code>%TEST_TIME_IN_SECONDS%</code> with a integer works, so it must be a syntax problem.</p>
  
  <pre><code>Set TEST_TIME_IN_SECONDS = 10800
  
  ScalabilityTester.exe -t 50 -dc "dsn=..." -q "SELECT..." -tt %TEST_TIME_IN_SECONDS% -o "...output" 
  </code></pre>
