Zoom in, AS3

Hi,

I would need to make the view in flash cs3 to zoom in a mc that is already in my stage and make this mc go in the centre of the view.
It is a 2D game, and I need to zoom to automatically go in the second level of the game.

I ve seen a lot of zoom effects but all of them are like magnifying glasses, through click.

Can anyone help with this? Can you show me any example?

Thanks a lot!
