Sorry, I wasn't very helpful.
PHP Code:
myArray:Array = [];
for (var i:int = 0; i < movieClipNum; i++)
{
//the push command adds an object to an array
myArray.push(new MovieClip());
}
Now your question isn't very clear regarding event listeners, but the point is that now you can access all of the created movieclips by looping through the array (or accessing a specific movieclip directly if you know what index number is is at).
Are you unhappy about using arrays? If you give some more detail maybe we can give you a more satisfactory answer!
