You can something like this:

```auto
for(i = 1; i <= 10; i++)
{
  mc = this["BR" + i];
  trace(mc._x);
}

```

Or something like this, if you dont have an instance name:

```auto
for(obj in this) // get all objects
{
  if(obj instanceof MovieClip) // only movieclip
  {
    trace(this[obj]._x);
  }
}

```

This is a notation and can be used to access variables much the way you do with your standard dot notation. So you can essentially do it the same as with dot notation. Just making sure that you are using subscript correctly…

```auto

var myVar0:Number;
var myVar1:Number;
var myVar2:Number;
var myVar3:Number;
var myVar4:Number;

for (var i:Number=0; i<5; i++)
{
   this["myVar"+i] = Math.random() * 10;
}

```
