A question about enterFrame and multiple instances

Hi,
Here is what I’m doing.
In the library of the FLa I have a symbol that is exported for actionscript with a class name of ‘aClip’.
I am placing multiple instances of it on stage as follows:

 
for (var i:int = 0; i < 10; i++) {
 var myClip:aClip = new aClip();
 myClip.x = 0;
 myClip.y = 50 + (50 * i);
}

Each myClip will move across the stage at 1 unit per frame. If I only had 1 instance on the stage I would implement as follows:

 
//make an enterFrame listener for the stage
this.addEventListener(Event.ENTER_FRAME, moveClip);
//make a function for the listener
function moveClip(e:Event):void {
 myClip.x += 1;
}

The problem I am having, is getting this to work for the multiple instances generated in the for loop.

I know this has been discussed before, but doing a search has been no help.

I would appreciate any help.
