function reference

Hi

I've got 2 static functions (self.),
playlist function is calling check_movie function in a loop.

I need to have the results stored in myarray and myhash.

I don't know how I can give references of myarray and myhash to
check_movie function so myarray and myhash are updated and not emptied
everytime I loop.

def self.playlist
myarray = new Array
myhash = new Hash

Movie.find(:all).each do |movie|
   check_movie(movie,myarray,myhash)
end

#use of myarray and myhash

end

def self.check_movie(movie,myarray,myhash)
  #fill myarray, fill myhash
end

return them

def self.playlist
myarray = new Array
myhash = new Hash

Movie.find(:all).each do |movie|
   myarray,myhash = check_movie(movie,myarray,myhash)
end

#use of myarray and myhash

end

def self.check_movie(movie,myarray,myhash)
  #fill myarray, fill myhash

  return myarray,myhash
end
