A new property for the Movieclip object

//All Movieclips have properties such as the x position: _x
//This code overwrites some of the Movieclip objects predefined //Methods and replace them with new ones.

//The new property is: anymovieclipname._depth
//This code will only work correctly if you use the duplicateMovieClip,
//attachMovie methods of the Movieclip object:

anymovieclip.duplicateMovieClip("newname",depth)
anymovieclip.attachMovie("linkage","newname",depth)
