Abstract

PURPOSE:To improve the versatility of a procedure by developing input data on a main storage at the time of starting the execution of a job step and transferring the input data on the main storage to the buffer of a user in the case of receiving an input request from a processing program. CONSTITUTION:The input data which is allowed to be described in the procedure 12 and developed by a procedure development process part 16 is written in a spool data set 13 with a job control sentence. And at the time of starting the job step, the input data is developed on the main storage by a step initiator 17 and the process program 18 can read the input data through an input data access part 21. Therefore, the job control part and the input data can be unitarily managed and the input data can be used in common as well as the job control sentence by putting the input data in the procedure 12.

Description

[Detailed Description of the Invention] [Summary] Input data for a job step is allowed to be written in a procedure, and this input data is expanded in main memory at the start of execution of the job step, and when an input request from a processing program is received. In this case, the versatility of the procedure is improved by providing a means for transferring the input data on the main memory to the user's buffer.

[Industrial application field]

The present invention relates to a manual data processing method in a procedure that allows input data to be placed in a procedure used when submitting a fixed job to a data processing system.

In order to avoid the waste of having many users write all of the job control statements (JCL) each time they process a fixed-format job, 2. A procedure is used that consists of a set of job control statements with (or more than one) definition information.

It would be desirable to further improve the usefulness of this procedure.

[Conventional technology]

The procedure contains the necessary job control statements to execute some job stenobucks.

Conventionally, input data to be given to a processing program started in a job step could not be placed in a procedure.

However, it may be necessary to use most of not only job control statements but also input data in common in each job. In such cases, it is not possible to place human data in the procedure, so input data must be provided externally by overriding the data definition statement (DD statement), or a data center for the input data must be created separately, and this By specifying the input data, it was necessary to standardize the input data.

[Problem that the invention seeks to solve]

As described above, according to the conventional method, input data cannot be placed in a procedure, so specifying input data that can be shared is complicated, and the versatility of the procedure may be compromised. Ta. However, the job control statement and input data are
Because they are managed separately, simply placing input data in a procedure does not allow the input data to be centrally managed together with job control statements.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a method that allows job control statements and input data to be managed in a unified manner, and allows input data to be placed in a procedure.
