Convert action script

[rudamina]

Hi, I need to convert this code to ActionScript 2 or ActionScript 3. I prefer ActionScript 2.

onClipEvent (mouseDown) {
   if (i>0) {
      return;
   }
   zoom = true;
   dir == 1 ? (dir=-1) : (dir=1);
   if (dir == 1) {
      pt = {x:_root.zoom_this._xmouse, y:_root.zoom_this._ymouse};
   }
}
onClipEvent (enterFrame) {
   if (!zoom) {
      return;
   }
   _root.zoom_this._xscale += dir*i*100/8;
   _root.zoom_this._yscale += dir*i*100/8;
   var pt2 = {x:pt.x, y:pt.y};
   _root.zoom_this.localToGlobal(pt2);
   _root.zoom_this._x -= (pt2.x-pt.x);
   _root.zoom_this._y -= (pt2.y-pt.y);
   i++;
   if (i == 10) {
      zoom = false;
      i = 0;
   }
}

Thanks in advance!
