Passing variables to a duplicated movie

just wondering if theres a way to pass variables to a duplicated movie.
Ill be creating duplicate movies very fast (about 20 per second)
and want them each to have differrent variables to work with.

duplicating with that , and i want to pass 3 variables to the new movie clip

dot.duplicateMovieClip(“dot”+currdot, this.getNextHighestDepth(), {_x: xpos, _y:ypos});
