Abstract

PURPOSE:To perform multi-task processing by a general-purpose computer system with no intervention of an operator by producing a job control language (JCL) in an application program (APP-P) and registering a JOB directly from the APP-P. CONSTITUTION:A basic JCL is previously produced in a JCL file. When a start request is given from a conversational terminal 1 when the computer back-up design (CAD) is carried out, a CAD main body 2 reads the JCL out of the JCL file. Then the names of computer back-up production (CAM) data output programs 3-5 to be started are added. Furthermore the parameters needed by the programs 3-5 of the drawings, the types of NC equipments, etc., to be outputted are added for production of the JCL. Then a JOB control table 10 of an operating system OS is opened and the contents of the produced JCL are successively written into the table 10. When this writing job is through, the table 10 is closed. Hereafter a desired APP-P is started when the OS carries out the JOB.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a general-purpose computer system. The present invention relates to a processing method for application programs, and particularly to a multitask processing method in a general-purpose computer system suitable for dividing processing of application programs.

[Conventional technology]

Conventionally, operators create JCL to run application programs, and in order to run multiple application programs, they must list JCL to run each application program.
An operator operates an application program by registering a job through a submit operation. This type of device is introduced in Kazuto Kenno (1970) published by Sangyo Tosho Co., Ltd., pages 248 to 249.

°f・ , [Problems to be solved by the invention] 1□′ The above conventional technology does not consider multitasking processing by dividing functions; Interrelated programs must be combined into one program. 2.
When a program becomes large enough to exceed the limits of the operating system, functions must be reduced. 3
, only the programs included in the JCL created by the operator will run, so when running multiple programs, the JCL
must be listed in Also, depending on the conditions, it is not possible to change the program to be started. There was a problem.

An object of the present invention is to enable multitasking processing to be performed in a general-purpose computer system without operator intervention.

[Means for solving problems]

The purpose of the above is to create a JCL in an application program, instead of an operator creating a JCL and registering a JOB through a submit operation, and directly posting the JOB from the application program to the JOB management table managed by the operating system. This is achieved by registering.

[Effect]

Create a file in advance with the basic JCL input. If it becomes necessary to start another application program while one application program is running, read the previously created JCL from the file and use it as necessary. , add parameters, etc., or create all necessary JCL within the own application, open the JOB management table managed by the operating system, write in a character image, and register the JOB. Thereby, when the registered JOB is executed under the management of the operating system, the target program can be operated.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a schematic diagram of a CAD-CAM system.

The operator starts up the CAD main body 2, interactively designs and drafts using the interactive terminal 1 during CAD execution, and saves the results as a CAD data output Kafka file 6. CAD data output Kafka file 6 This is a randomly accessible file that corresponds to each design/drafting drawing.When a modification occurs to a drawing, CAD data output Kafka file 6 is read out and the corresponding drawing data is saved at the time of CAD execution. Modifications and changes are made interactively from the interactive terminal 1, and a CAD data output Kafka file 6 is stored each time. CA that outputs NC data to NC drilling machines, NC milling machines, and NG lathes.
Conventionally, the M data output programs 3 and 5 are started after being registered in the JOB management table 10 by an operator submitting JCL for starting those CAM bodies from the interactive terminal 9. Input data to each NC device was output to a data output Kafka file 7 or a CAM data output magnetic tape 8.

This embodiment uses CAM data output cutter programs 3 and 5.
Start-up is not only based on operator submissions, but also CAD
A menu screen is displayed on the interactive terminal 1 during execution, and the CAM data output exit programs 4 and 5 are started directly from the CAD main body 2 according to the operator's selection.

FIG. 2 shows a multitask overview diagram and a JOB registration flow.

A basic JCL is created in the JCL file 11 in advance. When a startup request is input from the interactive terminal 1 during CAD execution, the CAD main body 2 reads the basic JCL from the JCL file 11 and executes the C that is about to be started.
Add the program name of AM data output cutter program 3 or 5.

Furthermore, parameters required by the CAM data output cutter program 3 or 5, such as the drawing to be output and the model of the N0 device, are added thereto to create a JCL.

Next, the JOB management table 10 of the operating system is opened, the contents of the created JCL are sequentially written, and after all the writing is completed, the JOB management table 10 is closed. After that, when the operating system 12 executes the above JOB, the target application program will be started.

Thus, according to this embodiment, application programs can be started mutually in a general-purpose computer system, so that improved operability and reliability can be expected, and more advanced NC control can be realized.

〔Effect of the invention〕

According to the present invention, since other application programs can be started between application programs in a general-purpose computer system, 1) the program can be divided in response to an increase in program capacity. 2) The capacity of one program becomes smaller and it becomes easier to decipher.
Program improvement and maintenance become easier. 3) It has the effect of improving operability for operators.
