Access the actionscript code of an externally loaded swf

1

I know in AS2 I could do this pretty easily … But am unsure of the syntax approach of AS3.

I want to have a main movie which will load in an external swf, which has AS code in its timeline. Then I wish to access the functions inside this external swf and control them from the ‘controller’ swf (the main movie).

Any ideas? this is what I propose ::::

// Main Movie

var swfLoader:Loader = new Loader();
var swfFile:URLRequest = new URLRequest("external-file.swf");
var container:MovieClip= new MovieClip();
swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoadedHandler);
var currentSWF:MovieClip = new MovieClip();


function swfLoadedHandler(e:Event):void 
{
    trace("swf loaded");
    currentSWF = MovieClip(swfLoader.content);  
    currentSWF.executeFunction(); 
}
container.addChild(swfLoader);
swfLoader.load(swfFile);


//-------------------------------------------------//


// External SWF


function executeFunction():void
{
    trace("call from external swf");    
}

from this - “call from external swf” should trigger …
Right!?
