<p>PURPOSE:To make divided display screens easy-to-see and at the same time to improve the operability of the title display system by displaying only the state display row of a specific working screen pointed by a working mode display flag with no reduction in case plural specific screens are divided and displayed. CONSTITUTION:In a divided simultaneous display mode, a state display row store area 320 stores the state display rows od plural specific screens (logical unit LU screens) which are simultaneously displayed. Then a working mode display flag 321 is prepared to display a working mode in response to the area 320, and these areas 320 are successively selected. Thus it is decided whether the LU screen corresponding to the state display row is working or not by reference to the flag 321 corresponding to the selected area 320. If so, only the state display rows of the corresponding areas are selectively displayed on the screen of a display 34. As a result, the state display rows of the unnecessary LU screens are never displayed at the parts except the state display rows. Furthermore the state display rows are displayed with reduction. Thus it is possible to obtain the easy-to-see divided display screen and to improve the operability in a display system.</p> |
