how to pass variables from loading swf to loaded swf?

parent/loading swf:

package{

import flash.display.Loader;

import flash.display.Sprite;

import flash.events.Event;

import flash.net.URLRequest;

public class LoadingSWF extends Sprite{

private var loader:Loader = new Loader();

public function LoadingSWF (){

loader.contentLoaderInfo.addEventListener( Event.INIT, onLoaderInit );

loader.load( new URLRequest( "ExampleB.swf" ) );

}

private function onLoaderInit( event:Event ):void

{

Object( loader.content ).init( "passing" );

}

}

}

/*=======================================*/

child/loaded swf:

package{

import flash.display.Sprite;

public class LoadedSWF extends Sprite{

public function LoadedSWF (){

}

public function init( value:String):void{

trace(value);

}

}

}
