WINDOW DISPLAY METHOD

PURPOSE:To seek a required window through the simple operation without revision of current pattern configuration by displaying a revised display order of each window in a way that each window is set to the display order with the highest position sequentially by a command from the user. CONSTITUTION:A window 1 is displayed on a highest position and a window 2 is displayed under the window 1 in a way as if the part of the window 2 were hidden under the window 1. Furthermore, a window 3 is arranged under the window 2 but not displayed because the window 3 is hidden under the windows 1, 2. In this state, the user gives a command it to the system that each window is displayed while its display position is being revised so that each window is sequentially displayed at the highest position. The current window sequence is revised while the information of the displayed position and the display order of the windows 1-3 displayed at present is remained and the window 2 is displayed at the highest position by the command from the user.
