Loading an external movie clip

Question

Hi team,
  Last time I wanted to load an external clip I could do it like this
on (release) {
          unloadMovieNum(1);
          loadMovieNum("whatever.swf",1);
So now I want to achieve exactly the same thing in AS3,
I have been looking at examples on the web but am getting all sorts of errors and basically don't know what I am doing.  I also want to know how to navigate to .swf files in a file structure, as I have to build an old school fscommand file structure for a cd-rom.
Any and all help greatly appreciated.
Cheers,
Sub

Hey worked it out guys!
var myLoader:Loader = new Loader();                     // create a new instance of the Loader class
var url:URLRequest = new URLRequest("whatever.swf"); // in this case both SWFs are in the same folder
myLoader.load(url);                                     // load the SWF file
addChild(myLoader);                                     // add that instance to the display list, adding it to the Stage at 0,0
But now I need to know.. How do I unload it?
Cheers
