title: Is there a need to set Objects to Nothing
body: <p>I always read that it is recommended to set objects to nothing, once I am done with them. But I normally use them only in functions inside forms.</p>
  
  <p>Isn't the reference lost and memory released when the function scope is left, regardless of setting objects to Nothing? </p>
  
  <p>i.e. is it really necessary to do:</p>
  
  <pre><code>Set db = Nothing
  Set record_set = Nothing
  </code></pre>
