Hi, im trying to get a deeper understanding on how as works, I was wondering:

> 

for(var i:int = 0; i \< 100; i++)  
{  
[INDENT]var s:Sprite = new Sprite();  
s.name = “sprite”+i;  
addChild(s);  
[/INDENT]}

var s is a reference to the the new Sprite  
new Sprite is stored inside memory at some place  
var s is also stored inside memory but only takes a small amount of space because it only needs to point to new Sprite?

the second time the loop runs, will the old var s be overwritten in memory? or will it be asigned to a new position in memory?

would it be beneficial if i typed something like this?

[COLOR=YellowGreen]s = null[/COLOR]  
[/INDENT] }
