title: Is there some advantage in use resourcestring instead of a const string?
body: <p>Would you tell me if there is some advantage (less sotorage space, increase speed, etc) in using:</p>
  
  <pre><code>resourcestring
      MsgErrInvalidInputRange = 'Invalid Message Here!';
  </code></pre>
  
  <p>instead of</p>
  
  <pre><code>const
      MsgErrInvalidInputRange : String = 'Invalid Message Here!';
  </code></pre>
