THIS PROGRAM SIMULATES THE GAME "snake". A STRING OF CHARACTERS MOVES ON THE SCREEN ACCORDING TO THE PRESS OF THE ARROW KEYS. IF IT TOUCHES ITSELF OR THE SCREEN BOUNDARY, THE PROGRAM TERMINATES. WHEN THE SNAKE MOVES, IN ARBITRARY SCREEN POSITIONS SOME DIGIT (1-9) APPEARS. THE OBJECTIVE OF THE GAME IS TO MAKE THE "SNAKE" "EAT" THE SAID DIGIT, SO THAT IT IS ADDED TO THE SCORE. WHEN A DIGIT IS "EATEN", THE SIZE OF THE SNAKE INCREASES BY THE NUMBER OF CHARACTERS EQUAL TO THE VALUE OF THE DIGIT. IN THIS VERSION OF THE GAME THERE ARE PROVISIONS FOR SAVING / LOADING TOO.
