FIG. 1 is a block diagram showing the configuration of a program management method in a time sharing system according to an embodiment of the present invention. In this embodiment, the program management method in the time sharing system includes a plurality of terminals 1, an input/output control section 2, a command starting section 3, a command table 4, a program file creation section 5, and a system program. file 6, time sharing program file 7, command statistics file creation unit 8, command statistics file 9, program file creation instruction file 1o, and system program input/output unit 11
and an instruction file creation section 12.

Terminal 1 is a user of the time sharing system,
This is a device for inputting commands and instructions by an operator, etc. (hereinafter simply referred to as a user, etc.).

The input/output control unit 2 controls input/output between the plurality of terminals 1 .

The command starting unit 3 searches the command table 4 when a command is input from the terminal 1, obtains starting information of a program corresponding to the command, and executes the program corresponding to the command.

The program file creation unit 5 creates a program file creation instruction file 1 at the time of starting the time sharing service.
0 and the command statistics file 9, the program corresponding to the command whose number of command usage satisfies the condition indicated by the program file creation instruction is selected from the system program file 6 via the system program input/output unit 11, and the program is time-shared. A ring program file 7 is created and a command table 4 is created.

The system program file 6 is a file in which all programs executable by the information processing system are stored.

The time sharing program file 7 is a file that stores a program corresponding to a command that matches the conditions indicated in the program file creation instruction input from the terminal 1.

The command statistics file creation unit 8 creates a command statistics file 9 by referring to the command table 4 when the time sharing service ends.

The program file creation instruction file 1o is the time sharing program file 7 input from the terminal 1.
This is a file that stores program file creation instructions when creating the . For example, in the program file creation instruction file 1o, a program corresponding to a command used for collecting n (positive integer) is stored in the time sharing program file 7. Program file creation instructions indicating conditions such as storing up to 30 programs corresponding to frequently used commands in the time sharing program file 7 are stored.

The instruction file creation unit 12 creates the program file creation instruction file 10 when a program file creation instruction for creating the time sharing program file 7 is received from the terminal 1 during the time sharing service.

Referring to FIG. 2, the command table 4 includes command names 21. Time sharing program file storage flag 22. Entries consisting of a program storage location 23, a program size 24, and a command use count 25 are stored for the number of commands. The time sharing program file storage flag 22 indicates that the program corresponding to the command name 21 exists in the time sharing program file 7 when it is on, and indicates that the program corresponding to the command name 21 exists in the time sharing program file 7 when it is off. Indicates that it does not exist in program file 7. The program storage location 23 indicates the storage location of the program in the time sharing program file 7 when the time sharing program file storage flag 22 is on, and indicates the storage location of the program in the system program file 6 when the time sharing program file storage flag 22 is off. Indicates the storage location in .

Referring to FIG. 3, in the command statistics file 9, the number of command usages 32 is set for each command name 31 in a table format.

Next, the operation of the program management method in this embodiment and the time sharing system configured as described above will be explained.

(1) First, we will explain how commands are executed and how command usage information is collected.

(2) When a command is input from the terminal l, the input command is passed to the command activation unit 3 via the input/output control unit 2.

(2) The command starting unit 3 searches the command table 4 using the command name 21 of the passed command as a key, obtains starting information of the program corresponding to the command name 21, and executes the program corresponding to the command. Specifically, the command starting unit 3 first stores the program corresponding to the command in the time sharing program file 7 based on whether the time sharing program file storage flag 22 corresponding to the corresponding command name 21 in the command table 4 is on or off. Determine whether or not it exists.

■ That is, when the time sharing program file storage flag 22 is on, the program corresponding to the command is stored in the time sharing program file 7.
Therefore, the command starting unit 3 quickly transfers the program corresponding to the command from the time sharing program file 7 to a memory (not shown) based on the program storage location 23 and program size 24 in the command table 4. Load and run.

On the other hand, when the time-sharing program file storage flag 22 is off, the program corresponding to the command does not exist in the time-sharing program file 7, so the command starting unit 3 selects the program storage position 23 in the command table 4 and the program. Based on the size 24, a program corresponding to the command is loaded from the system program file 6 onto the memory via the system program input/output unit 11 and executed.

■ When executing the program in ■ or ■ above, the command starting unit 3 will automatically execute the command usage count 2 corresponding to the command name in the command table 4, regardless of whether the time sharing program file storage flag 22 is on or off.
Increase 5 by 1.

■ The processes from ■ to ■ are performed every time a command is input.

■ Note that when there is a program file creation instruction for creating the time sharing program file 7 from the terminal 1 during the time sharing service, the instruction file creation unit 12 creates the program file creation instruction file 1.
Create 0.

■ At the end of the time sharing service, the command statistics file creation unit 8 stores the command usage counts 25 corresponding to each command name 21 in the command table 4 in the command statistics file 9. to collect command usage.

(2) Next, processing at the time of starting the time sharing service will be explained.

(2) When starting the time sharing service, the program file creation unit 5 reads the program file creation instruction file 10 and obtains a program file creation instruction indicating the conditions of the program to be stored in the time sharing program file 7.

[Phase] Next, the program file creation unit 5 reads the command statistics file 9, and selects the command name 31 corresponding to the command usage count 32 that satisfies the condition indicated by the program file creation instruction obtained in step (3) above.

■ Subsequently, the program file creation unit 5 selectively reads out the program having the selected command name 31 from the system program file 6 via the system program input/output unit 11, and uses time sharing to speed up command processing. Create ring program file 7.

@ At this time, the program file creation unit 5 also creates the command table 4 at the same time. Specifically, the program file creation unit 5 turns on the time sharing program file storage flag 22 corresponding to the command name 21 of the program written in the time sharing program file 7, and turns on the time sharing program file storage flag 22 corresponding to the command name 21 of the program not written. Turn off the time sharing program file storage flag 22. The program file creation unit 5 also writes the program storage location 23 and program size 24 in the system program file 6 or time sharing program file 7 of the program into the command table 4, and writes all 0s into the command usage count 25.

■ When the creation of the command table 4 for all commands is completed, the time sharing service is started.

〔Effect of the invention〕

As explained above, the present invention makes it possible to reduce the size of a time sharing system program file according to the number of commands used based on instructions for creating a program file from a user of the time sharing system. This has the effect that resources can be used effectively without using unnecessary file space.

Furthermore, when the size of the time sharing system program file is reduced, the time required for time sharing service start processing is also reduced.
