Instructions: Choose a number from the set of battleships in 1A (page 51). The cat asks you for a number and then searches for its position, asking you what number is at each position. It displays the number of "shots" needed when the number is found. Documentation: The script does a trivial linear search. Variables: "number" is the number you chose; "index" traverses the battleships; "found" is a flag that is set when the number is found. The instruction "letter (index) of [ABC...]" is a way of displaying character indices that are used in the game.
