Abstract

PURPOSE:To call a micro definition sentence by registering a sentence into a library only when the name of a job control macro definition sentence to be registered is not coincident with the name of a macro definition sentence registered in a system job control macro library to prevent the operation by a program other than the desired program. CONSTITUTION:A macro library control section 11 of a registration system is provided with a macro registration control section 16, a micro call control section 15 and a system macro table SYMACTB, and a micro call command section 13 is connected to the control section 15 and a macro registration indication section 14 is connected to the control section 16. Further, a job control macro library 12 is provided with a system job control macro library SYMC and a user job control macro library USMC and they are connected to the control section 11. Then the control section 16 recognizes the macro definition sentence name included in the registration indication of the indication section 14 and only when the name is not coincident with the library SYMC macro definition sentence name, the sentence is registered in the library 12 and the operation by a program other than the desired program is prevented.

Description

Detailed Description of the Invention (81) Technical Field of the Invention The present invention relates to a method for newly registering a macro definition into a macro library that stores a group of job control statements, that is, a macro definition. This relates to the method of registering a definition field.

(b) Technical background A job control statement is required to execute a job, but in order to solve the trouble of preparing a job control statement each time the same job is executed, a job control macro function is introduced. It is considered. The job control macro function is a function for submitting a job to a computer system by calling a job control statement in advance using a simple macro call statement or macro call command. Using this function not only eliminates the need to prepare job control statements each time, but also has the advantage that even people who do not know the system of job control statements can easily submit jobs to the system.

To use the job control macro function, define a job control macro in the job control macro library.

You have to register your body. There are two types of job control macro libraries: system job control macro libraries and user job control macro libraries. The former includes translation, combination editing, and
Contains macro definitions for execution, etc., and is provided by the system manufacturer when the system is installed. on the other hand,
The latter, the user job control macro library, stores job control macro definitions arbitrarily created by the user according to the purpose of use.

(C) Prior Art and Problems The job control macro definition registered in this manner is used by specifying the name of the macro definition using a macro call command or a macro call statement. At this time, the macro/definition program call control section first searches the user job control macro library using the given macro definition program name as a key.

If the desired macro definition does not exist there, the system automatically searches the system job control macro library. Therefore, if a macro definition with the same name as a macro definition stored in the system job control macro library exists in the user job control macro library, the macro definition in the user job control macro library will be called, and the desired You will no longer be able to call macro definitions for system programs that do this.

(d) Structure of the Invention This invention has been made in view of the above points, and when registering a user job control macro definition for a macro library including a system job control macro library and a user job control macro library, The above drawback is improved by registering the job control macro definition in the user job control macro library only when the name of the job control macro definition to be registered does not match the name of the macro definition registered in the system job control macro library. It is.

(f) Embodiment of the Invention An embodiment of the job control macro definition registration method according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram for explaining the method of registering a job control macro definition body, and FIG. 2 is a flowchart showing the operation thereof.

11i macro library control section, 12 job control macro library, 13 macro call instruction section, 14 macro registration instruction section, 15 macro call control section, 16 macro registration control section, SYMCTB system macro table,
SYMC is a system job control macro library.

11s11c is a user job control macro library.

The macro registration control unit 16 converts the macro definition given from the macro registration instruction unit 14 into a user job control macro 09415.
It has a function of registering in the January ISMC, a function of referencing the system macro table SYMCTR prior to registration, and a function of outputting a message to the macro registration instruction section 14 based on the result of the reference.

The system job control macro library SYMC stores all registered system macro definitions and exists on, for example, a magnetic disk storage device. The user job control macro library USMC stores user macro definitions registered according to the purpose of use by the user, and similarly exists on the magnetic disk storage device.

The system macro table SYMCTB stores the names of all macro definitions registered in the system job control macro library SMMC, and exists on, for example, a ROM type semiconductor storage device.

The macro call control unit 15 reads a macro definition that matches the macro definition name given from the macro call instruction unit 13 from the job control macro library 12, and expands it in memory. At this time, the macro call control unit 15 first searches for the user job control macro library USMC, and if the designated macro definition does not exist there, searches for the system job control macro library SYMC.

Next, the registration operation of the macro definition body will be briefly explained with reference to FIG.

When the macro registration control unit 16 receives a registration instruction from the macro registration instruction unit 14, it recognizes the macro definition name n1 included in the information (recognition of macro definition name). Next, the control unit 16 refers to the system macro table SVMCTB (system macro table reference) and determines whether the same macro definition name as the macro definition name nl specified for registration exists in the system macro table SYMCTB. Then, the system Jijibu control macro library SYMC
It is determined whether a macro definition name identical to the macro definition name n1 specified for registration exists in the file (nl exists?
). The macro definition name that is the same as the macro definition name n1 specified for registration here is the system job control macro library S.
If it does not exist in YMC, the designated macro definition is registered (registration). On the other hand, if the same macro definition name as the macro definition name n1 specified for registration exists in the system job control macro library SYMC, the macro registration control unit 16 registers the macro without registering the macro definition name n1. A message to the effect that "the specified macro definition name n1 is the same as the name of a macro definition already registered in the system job control macro library SYMC" is output to the instruction unit 14 (message output).

In response to this message, the registrant of the macro definition changes the name of the macro definition and issues a registration instruction again from the macro registration instruction section 14.

In this way, the system job control macro library SY
A macro definition with the same name as a macro definition registered in the MC will never be used in the User Job Control Macro Live 990.
3MC is never registered.

Note that it is possible to directly determine whether or not there is a macro definition name that is the same as the macro definition name specified for registration in the system job control macro library, without using a special storage unit (system macro table) as in the embodiment. The system job control macro library may be searched.

(f) As described in the detailed description of the invention, when registering a user job control macro definition, the name of the job control macro definition to be registered must be the same as the name of the macro definition registered in the system job control macro library. Since it is registered in the user job control macro library only when there is no match,
By calling the macro definition, it is possible to prevent programs other than the desired program from running.
