No one has ever explained to me how to do this

I have come across this problem many times and have never really been explained to how this can be done.

I want to create 10 movieclips from my library, then I want to name them incrementally (ross1, ross2, ross3 etc) then I want to use this name within the loop to change the width. Below is what I am trying to do but the syntax is VERY wrong. Can anyone help?

for(var i:int;i<10;i++){

var newCircle:MovieClip = new myCircle();
newCircle.name = "ross" + i;
addChild("ross"+i);

"ross"+i.width = 300;

}
