Filed: 1994-07-04
Abstract: PURPOSE:To prevent the generation of setting abnormality caused by erroneous operation by searching for a memory means corresponding to a selected screen by a display selection means when a display screen is selected by selection operation and displaying the selected screen when the memory means is YES and cancelling a request when the memory means is NO. CONSTITUTION:When a screen number is directly inputted by a ten-key, a CPU 18 for a PMC detects input operation to store the screen number in a register and searches for the display screen memory file of a non-volatile memory 24 on the basis of the stored screen number to discriminate whether the memory region of the address corresponding to the screen number is set to zero. When 1 is set, it is meant that screen display is prohibited and, therefore, a display device 29 displays to the effect that the display of the screen of the screen number is prohibited. When zero is set, since the screen display corresponding to the inputted screen number is permitted, the CPU 18 for the PMC executes the display of the screen corresponding to the screen number.
