<p>A special function program associated with each predetermined area on a tablet (21) is stored in advance in a read-only memory (ROM) (51). If a predetermined area on the tablet (21) is pointed with a pen (6) when a power switch (2) is turned on, then a central processing unit (41) (CPU) adds the special function program associated with the predetermined area pointed and which is stored in the ROM (51) to an ordinary software. Then, when the ordinary software is operated, the special program added to the ordinary software can be operated. Thus, the special function program is added to the ordinary software and the special function program can be operated on the ordinary software. <IMAGE></p> |
