Subject: Novice Question: Getting "bad file descriptor error" when trying to use gets in ruby 1.8.1 for windows

Hi I'm trying to run this code:
   	while (line = gets)  	 
   	  puts "The given line is #{line}" 	 
   	  if line =~ /^eval:(.*)$/ 	 
   	    puts "#$1 # => #{eval $1}" 	 
   	  end 	 
  	end

That I found on a tutorial website.  Ruby gives me this error when I try to run it:
>ruby guessnumber.rb
higuessnumber.rb:4:in `gets': Bad file descriptor (Errno::EBADF)
	from guessnumber.rb:4
>Exit code: 1

Why is this happening?
