PURPOSE:To prevent such a case where the reference data is forgotten by displaying a back-up screen at a part of an input guide screen. CONSTITUTION:When an input indoor screen is displayed in response to the designation, a back-up screen for reference data on the corresponding code names, etc., and a display areas designating field table 14 are stored in a back-up screen memory and a memory for the table 14 respectively. When a back-up command is received via a cursor, etc., an interruption display processing part 16 is actuated. Then the retrieval of an address and the access are carried out to a back-up area 13 of a partial area of an input guide screen. Then the back-up screen is displayed on the input guide screen based on the contents of the pick-up screen memory and the table 14. This simultaneous display of both screens eliminates such a case where the reference data is forgotten like a case where both the guide screen and the back-up screen are displayed with switching. |
