Array help

Hello
Can someone help solve this for me so I can get my head around how to use arrays. Would be much appreciated?!

I have one object which changes to a different size everytime a different button is clicked. I have this on the button.

object1._xscale = 100;
object1._yscale = 100;

object2._xscale = 65;
object2._yscale = 65;

etc, etc…

Now how would I put this in an arrray so I dont have to keep writing xscale, yscale everytime? In other words I want to be able to just write the values.
