Subject: Re: Array and instance variable problem?

Wolfgang, Thanks a lot for your detailed answer.

What I meant in my second message, is that when @indexes is a FixNum 
(not an Array).
This code is working as expected:

#!/usr/local/bin/ruby

require 'pp'
class Dummy
   def initialize
     @indexes = 1
   end

   def get_next
     @indexes = @indexes*2

     @indexes
   end

   def get_next_10
     all = []
     for i in 0..9
       all << get_next
     end
     all
   end

   def show_id
     puts @indexes.object_id
   end
end
d = Dummy.new

x = d.get_next_10
puts '##### show contents #####'
pp x
puts '##### show @indexes-id #####'
d.show_id
puts '##### show ids of Array elements #####'
x.each{|e|puts e.object_id}





The output I got is:

##### show contents #####
[2, 4, 8, 16, 32, 64, 128, 256, 512, 1024]
##### show @indexes-id #####
2049
##### show ids of Array elements #####
5
9
17
33
65
129
257
513
1025
2049


I am curious about this result, why is it not the same behaviour?

It's also always the same @indexes which got into the array, right?

Thanks a lot for your patience!
Maxime.
