How to Manipulate Movie Clips in an Array

Hello,
In AS3 I have an array of Movie Clips:


var page_array:Array = new Array();
page_array = [home_mc, about_mc, contact_mc];

I want to set properties in those memory clips, e. g.


home_mc.x=500;
about_mc.alpha=.5;

But I need to be able to reference them as array elements, e.g.


page_array[0].x=500
page_array[1].alpha=.5;

I don’t seem to be able to get the syntax right. I’m sure I’m missing some brackets or quotes, but I don’t know where to look.
Thanks for any help
Tony
