ok... i'm still not getting it.  i want the elegant way to do the last two lines in my Server initialize.  and please be kind - i'm just a programming hack, not a professional. =)

---------------------------------

module Toc44_all

 def toc44_all_system(cmd)
    the_pipe=IO.popen(cmd)
    res = the_pipe.read
    the_pipe.close
    return res
 end

 def toc44_all_twoargs(a,b)
    return "#{a} - #{b}"
 end

end

module Toc44_fw
  def toc44_fw_justme(arg)
     return "returning #{arg}"
  end
end

class Server
 def initialize
   my_type = "fw"
   extend eval("Toc44_all")
   extend eval("Toc44_#{my_type}")
   eval("def toc44_fw_system(args); return toc44_all_system(args);end")
   eval("def toc44_fw_twoargs(*args); return toc44_all_twoargs(*args);end")
 end
end

 svr = Server.new
 puts svr.toc44_fw_justme("howdy")
 puts svr.toc44_fw_system("dir")
 puts svr.toc44_fw_twoargs("hi","there")
