It's missing a # in front of (http://...) but this is trivial of course :-). If I launch the program without arguments I get: ../lcd.rb:61: Usage: ./lcd.rb [-s size] number (RuntimeError) The (RuntimeError) shouldn't be there. Furthermore if you pass a string like 123CIAO4 it will output 12300004. You can check more strictly for the input given to the program and print something like "1234CIAO4 is not a valid number" or as you wish.
