Help calling staticShape after creating instance?

In the following code I create an instance of staticShape called doorway.
how would I get the handle to this instance in order to update its position?
[/b]??? is there some function like: %item =GetStaticShape("fart") ???[/b]

%item = new StaticShape("doorway")
{
  position = localclientconnection.camera.getPosition();       
  rotation = "1 0 0 0";
  datablock  = CastlePiece;
};
