<p>PURPOSE:To reduce the erroneous input and to improve the operability in the coordinate input of coordinate data on a screen for which the information by an operator is required. CONSTITUTION:By preparing a table Q of coordinate data existing within the effective range by a coordinate data designation control function 3 within an information processor 13 based on effective range data 1 designated by an input device all on the screen display of an output device 14 and a designated coordinate 2 inputted by an input device a12, the coordinate data designation which is equivalent to the input of coordinate data exising in the approaching order from the designated coordinate 2 becomes possible. Therefore, by designating an effective allowable range, the selection of the coordinate data information within the effective allowable range where the coordinate designated by an operator is defined as a center is simplified and the input mistakes by the operator is reduced.</p> |
