FIG. 6 shows a flowchart of the program starting means 34.

When the control unit 3 is activated, a file 1n information input screen is displayed on the terminal 1. Input the file name and file organization to be processed on this screen. The input data enters the main body of the host computer 6 through a line and is passed to the control section 3 via the host computer's operating system 2.

As shown in FIG. 3, the file information management means 31 reads file information 51-1 from the file management information storage file 51 from the storage device 5 (step S3).
-1).

If file information 51-1 whose file name matches the file name input from the screen does not exist, the record format, record name, record length, and key length of file information 51-1 are displayed on terminal 1. . If there is no file information 51-1 that matches the file name or the file name input from the screen, the format, record name, record length, and key length data for record 1 will not be displayed. Ref-1-format, record name, record length, input from [terminal]
Key length data is not displayed. The record format, record length, and key length data entered from the terminal 1 enter the main body of the host computer 6 through a line and are passed to the control unit 3 via the host's operating system 2 (step S3]2). Based on the data input from the terminal 1, the file information management means 31 assembles the file information 51-1 shown in FIG. 2 and writes it into the file management information storage file 51 of the storage device 5.Step 531-3
