Passing Movie clips as parameters


I have a flash movie where I make several duplicate movies using this code:

 for(i=0; i < 5; i++) {
duplicateMovieClip(_root.clover, "clover"+i, i);

In the actions for my “_root.clover” movie clip, I have the following:

onClipEvent (enterFrame) {
this._x +=1;
this._y +=1

Is there anyway I can pass the current movie clips to another outside method and perform actions on it instead of referencing it from inside the movie clip?

For example,

onClipEvent (enterFrame) {

and have this excecuted in an outisde method:

outsideMethod = function(movieClip) {
movieClip._x +=1;
movieClip._y -=1;

Where movieClip could be any random variable, not the name of the movie clip.

Any thoughts?

Any help would be greatly appreciated.

Thank you for your time!
