title: VBA cannot dim a UInteger
body: <p>I try to dim an unsigned integer using the line:</p>
  
  <pre><code>dim curStart as UInteger
  </code></pre>
  
  <p>and on running, I receive the error:</p>
  
  <p>Compile Error
  "User-defined type not defined"</p>
  
  <p>Is there a reference library that is required in VBA to allow unsigned integers?</p>
  
  <p>I'm using Visual Basic for Applications 7.1.1068</p>
