Working with the MovieClip: Using stop() and gotoAndPlay()

   <source lang="java">

package {

   import flash.net.URLRequest;
   import flash.events.Event;
   
   public class Movies extends Sprite
   {

       {
           var loader:Loader = new Loader();
           loader.load(new URLRequest("movie.swf"));
           loader.contentLoaderInfo.addEventListener(Event.ruPLETE, makeMovie);
   
       }
       private function makeMovie(event:Event):void
       {
           var mc:MovieClip = (event.target.content as MovieClip);
           mc.gotoAndPlay("intro");
           mc.addEventListener(Event.ENTER_FRAME, stopMovie);
       }
       private function stopMovie(event:Event):void
       {
           try
           {
               if (MovieClip(event.target).currentFrame == 30)
                   MovieClip(event.target).stop();
           } catch(err:Error) {
               trace("oops...");
