Hi Aidy,

Here's some code, which should work for you.  Of course you'll have to
answer the questions as where to put the methods puts_on and puts_off
(or whatever you decide to name them).

====

# replaces Kernel#puts w/ do-nothing method
def puts_off
  Kernel.module_eval %q{
    def puts(*args)
    end
  }
end

# restores Kernel#puts to its original definition
def puts_on
  Kernel.module_eval %q{
    def puts(*args)
      $stdout.puts(*args)
    end
  }
end

puts "You can see me."
puts_off
puts "But I'm hidden."
puts_on
puts "But I'm viewable once again."

Eric
