Extra close curly bracket. Although this example was not intended to be complete, it still has one too many close curly backets. Delete the last close curly backet and have fun with applying to an example.
------------------------------------
Here is an expansion on the example to give you an idea how to use it.

this.createEmptyMovieClip("my_mc", this.getNextHighestDepth());
with (my_mc)
{
lineStyle(1, 0x000000, 100);
beginFill(0xffff00, 100);
moveTo(0, 0);
lineTo(0, 100);
lineTo(100, 100);
lineTo(100, 0);
lineTo(0, 0);
endFill()
_x = 100
_y = 100
}


this.createTextField("point_txt", this.getNextHighestDepth(), 0, 0, 100, 22);
var mouseListener:Object = new Object();
mouseListener.onMouseMove = function() {
var point:Object = {x:my_mc._width/2, y:my_mc._height/2};
my_mc.localToGlobal(point);
point_txt.text = "x:"+point.x+", y:"+point.y;
};
Mouse.addListener(mouseListener);
my_mc.onPress = function() {
this.startDrag();
};
my_mc.onRelease = function() {
this.stopDrag();
};

// Remember: The _x and _y properties of a movie clip represent the
// 0,0 coordinate of the movie clip, in terms of the _parent timeline.

// To get the _x and _y coordinates of a movie-clip, in terms of
// the global coordinate system, the point you're looking to convert
// is in fact the 0,0 coordinate of the movie clip.

// I was getting hung up trying to pass the _x and _y properties
// of the movie clip for coordinate conversion.

// Where: target_mc is a reference to some movie-clip,
// anywhere in a flash project.

var point: Object = {x:0,y:0};
target_mc.localToGlobal(point);

globalXCoord = point.x;
globalYCoord = point.y;

I get very strange results with the localToGlobal and globalToLocal APIs. Because the hitArea movie clip property doesn't seem to work for me, I resorted to writing my own. So I'd like to do this:

function setHitArea ( movieClip )
{
// We would like to use the hitArea property of the movie clip but it
// doesn't seem to work so we make a hitArea movie and use it.
//
// this.thumbnailMovie.hitArea = movieClip;

if ( ! movieClip )
{
movieClip = this.thumbnailMovie;
}

var origin = { x: movieClip._width / 2, y: movieClip._height / 2 };
trace ( 'o1: ' + origin.x + ', ' + origin.y );
movieClip.localToGlobal ( origin );
trace ( 'o2: ' + origin.x + ', ' + origin.y );
this.hitAreaMovie.globalToLocal ( origin );
trace ( 'o3: ' + origin.x + ', ' + origin.y );
this.hitAreaMovie._x = origin.x - movieClip._width / 2;
this.hitAreaMovie._y = origin.y - movieClip._height / 2;
this.hitAreaMovie._width = movieClip._width;
this.hitAreaMovie._height = movieClip._height;
}

But when I run it I get traces like this:

o1: 370, 5
o2: 27430, 293
o3: 352.7, 158.35

Now the movie clip I pass in is visible in the document which is 840 x 500 and so o2 should be a point within 840 x 500 but it's not. Also, the hit area movie has its origin and its parent origin and its parent origin... set at integer boundaries and so how the .7 and .35 got in there I have no idea.
