PURPOSE:To prevent the execution of a processing from being missed, and to execute a high-order menu without fail under a condition that low-order menus are wholly executed by executing the high-order menu under the condition that the low-order menus are wholly executed. CONSTITUTION:A setting means sets a processing level to a menu table so as to hierarchically show the executing order of a processing corresponding to each menu item, and a flag to show a processing state is stored corresponding to each menu item. When the execution of the menu item is instructed, a first discriminating means 3 refers the menu table 2 and investigates it to the instructed menu item whether the menu item at a low-order level exists or not. When such a menu item exists, a second discriminating means 4 investigates whether all the processings corresponding to the menu item at the low-order level are already executed or not. When one menu item not executed yet exists, a processing prohibiting means 5 prohibits the execution. Thus, the execution of the processing is prevented from being missed and the processing of the menu can be executed without fail. |
