PURPOSE:To make only arbitrary plural processing items executable by selecting processing items to be executed from the plural lower-rank processing items belonging to selected higher-rank items and executing the selected processing items. CONSTITUTION:A higher-rank item is selected out of executing processing items constituting a tree structure and, among the plural lower-rank items belonging to the selected high-rank item, a processing item to be executed is selected and the selected lower-rank processing item is executed. Therefore, it becomes unnecessary to execute and terminate the processing items one by one and the selection of an item to be executed from plural executing processing items constituting a tree structure becomes easier, and then, selected plural processing items are executed at once. |
