Dynamic screen control means that controls the screen to enlarge or reduce the display area according to the input of the target screen reduction command, and to enlarge or reduce the current display data, and static screen enlargement in the screen control command. Control command or static screen cotton 7J
A static screen control means that controls the screen to enlarge or reduce the display area according to the input of the % command and to enlarge or reduce the range of the currently displayed data, and a dynamic screen enlargement/reduction command or static screen control means. Control method selection means for selecting dynamic screen control means or static screen control means in accordance with input of screen enlargement/reduction commands, and display data sent from the screen control means, dynamic screen control means, or static screen control means. It is equipped with a display that

Function The present invention allows the user to dynamically enlarge the screen by using the above-described configuration.
By inputting a reduction command or a static screen enlargement/reduction command, the display area is enlarged or reduced and the current display data is enlarged or reduced, or the display area is enlarged or reduced and the current display data is It becomes possible to select expansion or contraction of the range.
