PURPOSE:To quickly display only the minimum necessary information on a CRT and to reduce the load of a computer, by dividing a screen according to the system and forming N types of optional divided screens according to the purposes to use these screens. CONSTITUTION:The corresponding display information is indexed from the screen display information 7 to produce the picture display request information 8. A CRT picture display processor 13 is started by a picture display request processor 12 and compares the screen display information 9 showing the screen which is presently displayed on the CRT with the information 8 with every divided screen. Thus the display is decided for the screens having no coincidence, and at the same time the display data to correspond to the display request screen are collected out of the display data group 14. Then a display data 10 is produced and displayed on the CRT. After the display of CRT, the information 8 is transferred to the information 9 and the information 8 is coincident with the information 9 until a new display request is given. Thus no change is given to the screen. |
