<p>PURPOSE:To produce a program that can be used in common to a keyboard device and a coordinate input device via a keyboard input control part only by converting the displayed characters into the key codes, and storing these key codes in a keyboard buffer. CONSTITUTION:When a coordinate input device A2 is pushed at a position (3, 2), the coordinates (3, 2) are given to a coordinate input device control mechanism C2. Then the means C2 converts the coordinates (3, 2) into the character coordinates (1, 1). A character code '32' corresponding to a character '2' displayed on a screen is obtained from a character memory B3 storing the character code corresponding to a character coordinate system B2. Then a key code '16' corresponding to the code '32' is stored in a keyboard buffer D1. Meanwhile the code '16' is given to a keyboard device control mechanism C1 and then stored in the buffer D1 with push of a key '2' via a keyboard device A1. Thus a program that can use the device A2 is produced via a keyboard input control part only.</p> |
