Sebastian,
My Ruby installation must be corrupt, as it doesn't recognize gets. 
When I try your solution, I get the following error message:

D:/scripts/ruby/f0.rb:10:in `gets': Bad file descriptor (Errno::EBADF)
  from D:/scripts/ruby/f0.rb:10

I'd assume the best way to correct this would be to reinstall Ruby? 
Would you agree?

Thanks,
PETERV
