The input identification unit 10 identifies data input from the keyboard and identifies each function tI! It calls the IyA units 20 to 70, and includes the file transfer classification shown in FIG. 2, terminal vA (command input computer side) file name, terminal side device name (equipment name), host side (control computer side) file name,
Enter file type 9 title and identify each function control unit 20
．． Control is transferred to 70. Each function is called according to the input value of the file transfer category shown in FIG. The transmission/reception control unit 80° 180 is a part in charge of communication t111111 between the command input computer 1.2 and the control computer 3,
Mainly file data, file management file data,
It transfers error codes, etc., and also performs line control when commands are simultaneously sent to the till16 computer from n command input computers.

The file securing unit 90 transfers the already registered file of the t111111 computer 3Il to the command input computer 1.2 side, and when it is desired to refer to it, the file area is stored on a fixed disk or floppy disk which is an external storage device of the command input computer 1.2. Perform processing to secure the The file access unit 100.degree. 210 performs a read process for a file in which data to be transferred is stored, and a write process for storing the transferred data in a designated file. Command identification unit 1 of control computer 311m
10 analyzes the command and file information received from the transmission/reception control 81siso and calls each function control section 120 to 170. The command identification unit 110 also performs identification of command input with respect to error message output. The file management file access Fg5190 performs information reading and writing processing for the file management file. The file management file is the only management file in the system that collectively manages information on files registered on the control computer 3 side, including file name, record name, file size, file type, and title for the file. It has items such as information as information. File registration section 2
00 has the same function as the file securing unit 90 on the command input computer 1.2 side.
Based on the file information received from the side, the control computer 3
Performs processing to secure a file area on a fixed disk, which is an external storage device. Contrary to the file registration section 200, the file deletion section 220 deletes files from the control computer 3 in response to a file deletion command received from the command input computer 1.
This process releases the file area already reserved on the fixed disk, which is an external storage device, and deletes the data in the file.

Next, the relationship between the file management file on the control computer 3 side and each data file will be described. The file management file is a management file having information on files that serve as indexes of data files registered in the control computer 3.

Immediately before registering, referencing, or deleting a data file, be sure to record, refer to, or delete the file management file for each file. Therefore, the code under the file management file has a one-to-one correspondence with the data file.
