Realization of a game with good operating properties using a personal
computer is made possible. Because the home position of a catcher's mitt
character determining a pitch course can be determined, and movement to
the home position performed, by a single key operation of the keyboard,
return to the home position can be performed with ease similar to that
possible when a player removes a hand from a joystick or similar in
dedicated game equipment to cause return to a home position, so that
operating properties are improved.
