**      Version:        1.3 More bug fixes...
**      Disclaimer:
**      My compiler did not like splitting System.out lines into multiple lines.
**      Be it either because of Java 7 or 8, I do not know, but it would not
**      compile if I split up the print statement.
**
**      Points are not influenced if the number is invalid, out of range, or part of a command.
