Subject: Re: calling methods, beginner help

Thanx for your answers. I know: never use global variables ... and no 
monkey patching ...I'll try.

I'm programming for sketchup api. My code structure is like this

module Module

class Do_this
def initialize()
end;end;


class Do_that
def initialize()
end;end;



#When I want to execute a command I have to add a button in the GUI of 
Sketchup, like this:


cmd = UI::Command.new("Do this")  {Module::Do_this.new()}
UI.menu("Plugins").add_item(cmd)

end#module
#-------------------------------------------------------
So as markus suggested

class Test
  def initialize
    @array = [10,10]
  end

  def product
    @array.inject(1) { |s,v| s *= v }
  end
end

And than run *outside* the class:

object = Test.new
object.product  # => 100


Is in my case impossible: it has to run *inside* a class

Just did some quick reading about procs, is that an option???

For extra clearness:

My class Do_this and my class Do_that both have to use that method..
They both use the same variable and both have to apply the same 
operations on that variable (amongst other things of course)..


Please help
