The display control unit 19 receives the information from the mouse memory 18.
The information is sent to the CRT 20 to display the above-mentioned icon on the display screen of the CRT 20. Information selected by the mouse 11 using icons displayed on the display screen is input to the CPU 15.

The CPU 15 searches the display management table memory 17 based on the input information, reads out the display information of the corresponding display screen, and stores it in the display control memory 16. The display management table memory 17 stores a plurality of management tables and display data corresponding to each display screen, and each management table is assigned a start record number with information for one screen as one unit, as shown in FIG. , an end record number, a pointer to display data, and a pointer to the next management table. FIG. 4 shows an example of connection of management tables.

The display control section 19 takes out the display data stored in the display control memory 16 and displays it on the display screen of the CRT 20.

FIG. 5 is a display example of this embodiment. In this example, it is assumed that five records can be displayed on one page, and the first page is currently displayed. At this time, records numbered 1 to 5 are displayed on the first page, but if the user wishes to specify the 11th record from this display screen, the mouse 11 is operated to display the record selection icon 21. Since there are currently 12 records, this icon 21 displays 12 divided areas, of which 5 areas from the left are displayed in reverse video. This corresponds to the position of the currently displayed record (records 1 to 5). Here, specify the position of the 11th divided area among the divided areas of the icon 21 using the mouse 11, and press the left button of the mouse 11 to display the display screen containing the 11th record, that is, the display screen of the 3rd page. and the cursor moves to the 11th position.

FIG. 6 is a flow chart for explaining the operation of the above embodiment. If the left button of the mouse 11 is pressed (step A1), the display management table memory 17
The total number of records is determined by (step A2). The record selection icon 21 is divided and displayed according to the total number of records (step A3). Next, the record number range of the currently displayed record is checked from the currently specified management table in the display management table memory 17 (step A4), and the divided area at the position corresponding to this record number range is reversed. Display (step A5). Thereby, the position of the currently displayed record with respect to all records can be known on the record selection icon 21.
