[Flash 8] Manipulating objects in an array?

Hi.

This should hopefully just be a quickie.

I’m slowly starting to learn Flash and Actionscript and right now I’m a bit more stuck than usual.

I have an array, “container”, to which new movieclips are added by clicking a button. When they are added they are given a name, “pic” + i, and are added at the corresponding index “i”.

Now, what if I want to change the position of a certain movieclip in the array or alter its alpha value?
I tried something like:

[FONT=Courier New]container*._x = x;[/FONT]

but since nothing happens that’s obviously not the way to do it.

Any and all help is welcome.
