Here's my "real" code (BlogData.rb):
<code>
class Timed
    attr_reader :time
    def initialize
        @time = Time.new # <-- line 23
    end
end

class Entry < Timed
    attr_reader :title, :description
    def initialize(titleS, descS)
        super()
        @title = titleS
        @description = descS
        @comments = Array.new
    end
    def to_s
        "E : #{@title} -- #{@description}  [#{@time}]"   
    end
end

class Comment < Timed  
    attr_reader :text
    def initialize(commentS)
        super()
        @text = commentS
    end
end

e = Entry.new('title1','desc1')
puts e
</code>

My shell:
 >ruby BlogData.rb
E : title1 -- desc1  [Fri Jan 23 15:11:27 Westeurop�ische Normalzeit 2004]
 >Exit code: 0

And here's another file in the directory (t.rb):
<code>
require 'BlogData'
e = Entry.new('title1','desc1')
puts e
</code>

My Shell (with 'puts e' in BlogData.rb deleled):
 >ruby t.rb
./BlogData.rb:23:in `initialize': wrong number of arguments(0 for 2) 
(ArgumentError)
    from ./BlogData.rb:23:in `new'
    from ./BlogData.rb:23:in `initialize'
    from ./BlogData.rb:32:in `initialize'
    from t.rb:17:in `new'
    from t.rb:17
 >Exit code: 1

It doesn't work if I "require" my code in another file.

Writing "def initialize()" or "def initialize" doesn't make a 
difference, does it?

Cheers!
