How to set property to a dynamic button?

1

Hello, friends

some code look like this:

var i = 1;
while(i < 6){
    newX = new Number(i * 25);
    newY = new Number(187);
    newW = new Number(22);
    newH = new Number(22);
    _root.createClassObject(mx.controls.Button, "button"+i, i, {label:i, _x:newX, _y:newY, _width:newW, _height:newH});
    i++;
}

"button"+i.enabled = false;

the last line is syntax error, is there any way can I set property to a dynamic variable like above?

or how can I concat a string and a variable as a new variable?

I’d very appriciated if any one can help me out, thanks in advance.
