A Game of Number Guessing

A Game of Number Guessing is a number guessing game written in BASIC. The twist is that the number to be guessed changes each turn. The computer has a base number and a jump number in mind, both are randomly chosen. The player must guess the base number, but after each guess the base number is increased by the jump. When exceeding 100 the number wraps around. The difference between the player's number and the base is shown after each turn.
