Send variable to loaded file

1

Hi, im loading external files and i need send one variable inside there. i create one function to load files:


var request:URLRequest;
var loader:Loader;
var percentLoaded:Number;

function loadMainBox(contClip:MovieClip,url:String)
{
	request = new URLRequest(url);
	loader = new Loader();
	
	loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
	loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadComplete);
	loader.load(request);
	
	if ( contClip.numChildren > 0 ) Tweener.addTween(contClip, { alpha : 0, time : baseTime, onComplete : function() { contClip.removeChildAt(0); contClip.alpha = 1; } });
	contClip.addChild(loader);
}

function loadProgress(event:ProgressEvent):void 
{
	percentLoaded = event.bytesLoaded/event.bytesTotal;
	percentLoaded = Math.round(percentLoaded * 100);
	
	loaderClip.perc.autoSize = TextFieldAutoSize.CENTER;
	loaderClip.perc.text = String(percentLoaded + "%");
	Tweener.addTween(loaderClip, { y : 300, alpha : 1, time : baseTime * 1.5 });
};
function loadComplete(event:Event):void 
{
	Tweener.addTween(loaderClip, { y : -300, alpha : 0, time : baseTime * 1.5, transition : "easeInBack" });
};
