Class Clarification

Ok, I just had a few things I need clarified.

  1. I can have one public class per package?
  2. package “name” { … “name” refers to directory? Because I tried giving my package a name and got an error.
  3. When extending a class, say we have class Shape {
    and I want to extend class Square {
    I would then create a… var myShape:Shape = new Square(12);
    or var myShape:Square = new Square(12);

Anyhow, those are some things I’m not understanding right now. Thanks if you get help me, I’ve been going through the help files and I’d like to get past some of this stuff so I can get on to the better stuff.
