An area for displaying the contents and contents of records selected last time and the time before last is defined, and an area is defined for sequentially writing the selected record numbers into a storage area within the program.

This area includes a display range 101 that displays the currently read data, a display range 102 that displays the options stored in the currently read data, and a display range that displays the previously read data. 103 and display range 10, which is the part that displays the data read two times before.
4.

FIG. 2 shows a file layout in one embodiment of the present invention. In FIG. 2, the file used in this embodiment is composed of a key 201, a document 202, and a plurality of options 203, and the options are composed of a selected document 204 and a jump key 205. The file in this example is a randomly accessible file as shown in Figure 3, and each record in the file has a record number used as a search key, information to be displayed on the screen, a display of options, and a list of each option. The record number to be displayed when selected is stored.

In one embodiment of the present invention, there are a means for selecting a fixed record number immediately after startup, a means for searching for the next record according to an instruction from an operator, and a means for moving display contents to the previous time and the time before the previous time. means for additionally writing into an area for storing the record number of a record that has been selected; means for transporting data selected two times before last by a specific operation to the display area; and means for transporting data selected last time to the current display area; and an area for storing the record number. and means for deleting the last record and displaying the previous 44 consecutive records in an area of the screen for displaying data from the previous two times.

In one embodiment of the present invention, immediately after startup, a specific record,
For example, a record with a key of 0000 is displayed on the reading screen.

Here, when the operator inputs a number from 1 to 5, a key corresponding to each number is obtained and the file is read out.

Once the file has been successfully read, the data displayed in the display range 101 is moved to the display range 103, the content of the data read this time is displayed in the display range 101, and the data read this time is displayed in the display range 102. Displays the options stored in .

Also, the key of the data read this time is added to the area for storing the progress of selections in the program.

If the operator further inputs a number from 1 to 5, the key for the next data to be read corresponding to each number is obtained and the file is read. Once the file has been read, the data displayed in the display range 103 will be transferred to the display range 104.
, the data displayed in the display range 101 is transferred to the display range 103, the display range 101 displays the contents of the currently read data, and the display range 102 displays the data stored in the currently read data. Display options.

Also, the key of the data read this time is added to the area for storing the progress of selections in the program.

By repeating these processes, the data of this structure is displayed on the screen. In the present invention, specific designations other than 1 to 5 are defined as operations for returning to the original state.

If an operation to return to the original state is instructed when the operator inputs a choice, the last record in the area that stores the progress of choices in the program is deleted, and the data in the display range 103 is transferred to the display range 101.
