Using createEmptyMovieClip()

[color=blue]c_mc2 = _root.createEmptyMovieClip(“main_text”, 4);
c_mc2._x = 0;
c_mc2._y = 359;[/color]

If i use this method to create an empty clip and then once i am done with the clip i unload the movie which was previously in it, what happens to the clip. Do i have to re-create it if i want to reuse the empty movie clip again with the same name?

please help me someone!
