How do I name a MovieClip drawn with as3?

I am trying to draw a set number of squares in a grid type layout and have pretty much gotten it to do what I want. The problems is that I want to be able to manipulate each square individually later on and I'm pretty sure I need to assign each one a unique instance name... something like "square_0_0" all the way down to "square_10_10" (it's a 10x10 table of squares).

Anyway... how do assign a unique instance name to each square as it's added to the stage? I attached the code I currently have running. Thanks in advance for any help you can offer.
