[How-to] pass a value to loaded SWF?

Hi all,

Is it possilble to pass a value from “main.swf” to “abc.swf” ???
like … value1 = 100;
or …?? i have to use the SharedObject ???

 
// ########## main.swf ##############
 
var value1:Number = 100;  // <-- pass this value to abc.swf
 
var f:String = "abc.swf";
var ldr:Loader = new Loader();
var container:MovieClip = new MovieClip();
var req:URLRequest = new URLRequest(f);
 
ldr.load(req);
addChild(container);
container.addChild(ldr);

Thanks for helping
