<p>PURPOSE:To facilitate programing by unifying menu pictures for branch retrieval, function setting of input keys displayed on these pictures, and position coordinate designation of keys into one system. CONSTITUTION:When a menu picture for retrieval is generated and displayed on an information display device 5, function information and position coordinate information are accessed from a coordinate file in accordance with picture identifying information corresponding to the displayed menu picture for retrieval. Position coordinate information, which is accessed from the coordinate file 20, coinciding with touch position coordinates inputted from a touch sensing input device 3 is searched. Function information in the most significant digit of position coordinate information coinciding with said coordinates is branched to a corresponding function processing routine. Since individual information for every picture are accessed collectively and position coordinate information is searched in the accessed record unit, these programs can be shared even if the number of menu pictures for retrieval is increased.</p> |
