Actionscript 3 :: Accessing The Class Members?

I have a class ABC:

class ABC
{
var l:Label=new Label();
var m:MovieClip=new MovieClip();
}

Given an instance of class ABC, e.g. obj:

var obj:ABC=new ABC();

I need to access both obj.m and obj.l. Say m has an eventlistener fl_listen which gets triggered on a mouse click:

function fl_listen(event:MouseEvent):void
{
var k=event.target;
}

Within this handler, I can access the MovieClip of ABC class. However, my requirement demands to access the object of Label in the ABC class too.
