ActionScript 2.0 :: Duplicate Mc From Library & Attach A Script?

I duplicate a MC from my Library and arrange on stage, using:

for (var x=0; x<4; x++){
for (var y=0; y<4; y++){
this.attachMovie("dot","dot"+ ++depth, depth)
this["dot"+depth]._x =515.9 + x * 17.2
this["dot"+depth]._y =199.2 + y * 17.2
}
}

however, i also have a script which i wish to attatch, so the MC becomers draggable. I normally use this: (The Mc contains a button)

on(press){
this.startDrag();
}

[Code]....
