Subject: Basic OO Class question

Hi All

I am try to get up to speed on several things at once; namely, OO and
also Ruby.  I have written a bunch or Ruby scripts to perform various
text processing tasks but I think I want to start learning something
about OO Programming.  I do have the book "Programming Ruby" and it is a
great help.

My question is related to writing a class for something like a polygon.
It can be described by a few integer and string properties. So I could
do something like this snippet:

class Zone

    attr_accessor :type, :length

    def initialize(type, length)
      @type = type
      @length = length
    end

end

testZ = Zone.new("Rad", 20.1)

Here is what I don't know how to do.  How do I add an array of integers
to this class?  It would need to be of variable length.

Sorry for the basic question?

Kev
