Thank you for the correction Bertram, I've never used a mailing list =
before and it didn't occur to me. Hopefully it's in the right place now.

I'm having a bit of a problem accessing variables in an instance of =
GServer.
What I would like to do is make a hash that is effectively global to the
current thread.

-/Server.rb
require 'gserver'
require 'connect.rb'

class TestServer < GServer
  def initialize(port =3D 4000, *args)
    super(port, *args)
  end
  def serve( io )
      @test_hash =3D Hash.new
      connect(io) #Defined in connect.rb
    loop do
      str =3D io.gets
      parser(str,io)
    end
  end
end

The way that I'm doing it doesn't allow each thread to have it's own =
copy of
@test_hash and that's my problem. I need each thread to be able to =
change
the data stored in the hash without affecting the data stored in the =
hash
for all threads. I'm sure that my understanding of scope and GServer =
itself
is causing my problem, but I just don't know what to do to fix it. I was
thinking that I could pass the hash as a parameter to the connect =
function
but that would quickly become a problem as it would need to be passed to
several other functions after that and if possible I just don't want to =
have
to use that many extra parameters in my functions. Any help would be
appreciated.
