Abstract

PURPOSE:To improve the operability of this starting command determining system by providing the determining system with a file format deciding means and a start command character forming means and connecting the system to a command starting program for starting a program in accordance with a command character string for instructing the operation of a program stored in an electronic computer. CONSTITUTION:The starting command determining system 1 is connected to the command starting program 2 and constituted of a file control information acquiring means 11, the file format deciding means 12 and the starting command character string forming means 13. At the time of receiving a command character string from a terminal equipment 3, the program 2 stores the received command character string in an command character string storing area 51 in an operating system(OS) storage area 5 and then transfers control to the system 1. Since the sort of the command to be started is automatically determined by a file specified by a user through the character string, the generation of errors due to user's command instruction is reduced and the operability is improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for determining a startup command, and in particular, in a command startup program in an information processing system operated in the TSS method, a program specified by a user is stored. This invention relates to a startup command determination method that automatically determines a command to launch using file management information of a file.

[Conventional technology]

In general, the startup command determination method in a TSS type information processing system is such that the user knows in advance the format of the file in which the program to be launched is stored, and if the file format is a file for storing a load module, then the method shown in Figure 4 The user decides to instruct the command string to start the load module as shown in
If the file format is a file format for storing a source program, the user himself or herself decides to specify a command string to start the source program as shown in FIG.

[Problem to be solved by the invention]

The conventional startup command determination method described above has the disadvantage of low operability because the user must recognize in advance whether the startup program is a load module or a source program and then select the command to start. There is.

Another drawback is that the storage file of the program to be started is often incorrectly specified in the command string, resulting in poor operability.

[Means to solve the problem]

The startup command determination method of the present invention includes a file management information acquisition means for acquiring management information of a file in which a program is stored from a management area of the file in order to know whether a program to be activated by a user is a load module or a source program. a file format determining means for determining the format of a file in which a program is stored from the file management information retrieved by the file management information acquisition means; and determining a command to be activated from the file format determined by the file format determining means. and a startup command string creation means for creating a command string to be passed to the command startup program, and is used when connected to the command startup program that starts the program according to the command string that instructs the operation of the program on the computer. It is characterized by being

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is a block diagram showing an embodiment of the present invention, Fig. 2 is a flowchart showing the processing flow of the activation command determination method of the invention, and Fig. 3 shows an example of a command string received from a terminal device. FIG. 4 is a diagram showing an example of a command string for starting a load module, and FIG. 5 is a diagram showing an example of a command string for starting a source program.

The activation command determination method 1 of this embodiment is used in connection with the command activation program 2, and is comprised of a file management information acquisition means 11, a file format determination means 12, and an activation command string creation means 13.

When the command starting program 2 receives a command string as shown in FIG. 3 from the terminal device 3, it stores the received command string in the command string storage area 51 in the storage area 5 of the operating system. After storing, control is passed to startup command automatic determination method 1 of the present invention.

Here, the command string includes the command name indicating the type of command, the file name of the file in which the program is stored, the program name of the program to be started, and the operation of the program, as shown in Figure 3. It consists of a sequence of multiple parameters. In addition, in FIG. 3, the letters "DO" are used in the command name as an example.

The file management information acquisition means 11 is first given control when the startup command determination method 1 operates, and opens the program storage file 4 specified in the command string and acquires the file management information 411 in the file management area 41. . Thereafter, the file management information acquisition means 11 closes the program storage file 4 and transfers control to the file format determination means 12 together with the file management information 411 of the program storage file 4.

When the file format determination means 12 is given control by the file information acquisition means 11, it determines the file format of the program storage file 4 by referring to the file management information 411 passed from the file management information acquisition means 11. If the program storage file 4 is a file for storing a load module or a file for storing a source program, control is passed to the startup command string creation means 13. At this time, the file format of the program storage file 4 is also notified. If the file format is neither a load module storage file nor a source program storage file format, the file format determination means 12 notifies the command activation program 2 of an error.

The activation command string creation means 13 refers to the file format received from the file format determination means 12 and determines the command to be activated, and then creates a new command string to be passed to the command activation program 2. This new command string is a command string with the command name "CALLJ" as shown in Figure 4 if the file format is a file format for storing load modules, and a command string with the command name "CALLJ" if the file format is a file format for storing source programs. As shown in Figure 5, this is a command string with the command name rEXECJ.The startup command string creation means 13 stores the created new command string in the command string storage area 51 in the storage area 5 of the operating system. After that, control is returned to the command starting program 2.

Next, the operation of the activation command determination method 1 of the present invention will be explained with reference to FIG.

Steps 21 to 23 in Figure 2 are startup command determination method 1
Of these, the operation of the file management information acquisition means 11 is shown, steps 24 to 25 are the operations of the file format determination means 12, and steps 26 to 29 are the operations of the startup command string creation means 13.

First, the program storage file specified in the command string is opened (step 21), and the file management information 411 of this file is stored in the file management area 41 on the magnetic disk.
1 (step 22). Obtain information such as file organization, record length, block length, etc. of this file. After obtaining the file management information 411, the program storage file 4 is closed (step 23).

Based on the file management information 411 acquired by the file management information acquisition means 11, the format of the file in which the program is stored is determined (step 24), and if the file is a file for storing a load module or a file for storing a source program. Control is passed to the startup command string creation means 13. If the program storage file 4 has a file format different from either the load module storage file or the source program storage file, the command activation program 2 is notified of an error (step 25).

Steps 26 to 29 are steps for determining a command to be activated based on the file format obtained by the file format determining means 12 and creating a new command character string. If the file format obtained by the file format determining means 12 is a file format for storing a load module (step 26), a new command string for starting the load module is created (step 27), and the file format determining means 12 creates a new command string for starting the load module (step 27). If the obtained file format is a file format for storing a source program, a new command string for starting the source program is created (step 28). Thereafter, the new command string created by the startup command string creation means 13 is stored in the command string storage area 51 in the storage area 5 of the operating system (step 29).

Thereafter, the command activation program 2 refers to the new command string and activates the command using the same interface as before.

〔Effect of the invention〕

As explained above, the startup command determination method of the present invention is as follows:
Since the user does not need to know in advance whether the program to be started is a load module or a source program and then select the command to be started, this has the effect of improving operability.

In addition, since the type of command to be automatically started is determined based on the file specified by the user in the command string, it is possible to reduce errors made by the user when issuing commands, and improve operability. effective.
