sorry, wrong values in M.platform_dependent_code method:

module M

   def M.print_platform
      print "Platform is..." + M.platform_dependent_code() + "\n"
   end


   case RUBY_PLATFORM
   
      when /solaris/i then
         def M.platform_dependent_code
            "Solaris"
         end
      when /linux/i then
         def M.platform_dependent_code
            "Linux"
         end
      when /win/i then
         def M.platform_dependent_code
            "Windows"
         end
      else
         def M.platform_dependent_code
            "unknown"
         end
     end
end

M.print_platform
