title: How could I say "when" in ActionScript 3?
body: <p>I am learning ActionScript 3 rigth now and I have this code:</p>
  
  <pre><code>stage.addEventListener(MouseEvent.MOUSE_MOVE, mouse_move);
  
  function mouse_move(event:MouseEvent): void
  {
  
      ourMirilla.x = mouseX * 1.85;
      ourMirilla.y = mouseY * 2 - 1244.25;
  </code></pre>
  
  <p>I would like to add something like this:</p>
  
  <pre><code>stage.addEventListener(MouseEvent.MOUSE_MOVE, mouse_move);
  
  function mouse_move(event:MouseEvent): void
  {
  
      ourMirilla.x = mouseX * 1.85 WHEN MOUSEx IS (&gt;35,&lt;55);
      ourMirilla.y = mouseY * 2 - 1244.25 WHEN MOUSEy IS (&gt;35,&lt;55);
  </code></pre>
  
  <p>How could I express that in ActionScript 3? </p>
