Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a group definition storage method for registering group information in a data set to be processed and performing group processing.

[Conventional technology and problems]

Group command functionality in source management programs (GEM) has traditionally been effective only within a single GEM session. Therefore, even though the same thing is executed, each time the GEM is activated, a group to be processed is defined in some way, and various types of processing are performed on that group. You can also screen edit (e.g. FSO) some members of a partitioned data set.
When processing one member, conventionally, after processing of one member,
Again, other members of the same data set must be called.

In this way, in the past, the task of defining a group was extremely burdensome, or when referencing and updating multiple members, other members of the same data set had to be called each time.
There were various problems with the operability of data sets.

[Object of the invention] The present invention solves the above problems, and includes:
The purpose is to reduce the burden of group definition work, facilitate access to members, and improve the operability of data sets by registering group definition information and group information on data sets. It is.

[Structure of the invention]

In order to achieve the above object, the group definition storage method of the present invention groups modules or members on a data set, provides a group definition management block on the data set, and stores the name of the group in the group definition management block. This is characterized in that definition information consisting of information specifying modules or members belonging to the group is written.

[Embodiments of the invention]

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

Figure 1 shows the registration status of specified group definition information, Figure 2 shows the registration status of group information at the time of GEM library initialization, and Figure 3 shows the registration status of group information at the time of module registration. The figure shown in FIG. 4 is a diagram showing the group registration status of members of the segmented data set. In the figure, 1 is
GEM library (processing target data set), 2
indicates a partitioned data set, 3 indicates a group name, and 4 indicates a member.

The present invention registers specified group definition information (group name and group attributes) in a processing target data set (GEM library in the source control program). Furthermore, when initializing the GEM library, group information for all modules, or when an owner is specified when registering a module, group information for modules with that owner name, such as a group common to users or Automatically register user-specific groups in the GEM library. It also has a function to output a list of group definition information (specified groups or all groups) at any time, and a function to delete group definitions that are no longer needed. By doing this, the group definition information (group name and group attributes) is registered, so you can omit the work of defining the same group every time.
Since groups common to all users and groups for individual users are registered, ease of use is further improved. Here, a module corresponds to a member of a partitioned data set.

You can also group multiple members of a partitioned data set, make the partitioned data set consist of a data set name, a group name, and a member, and refer to and update all grouped members with a single call. enable. This will be explained below with reference to FIGS. 1 to 4.

When registering specified group definition information, for example, use the group control statement GROUP GROUP1, MODNAME=(MO1,
MO2, MO3) GROUP When GROUP2, TYPE=SPL100 is input, group definition information is registered in the group definition management block of GEM library 1 as shown in Figure 1. The above group control statement means that the first part is an instruction to group three modules with module names MO1, MO2, and MO3 into group 1, and the second part is a command to group three modules with module names MO1, MO2, and MO3 into group 1.
This means that the command is to place modules written in SPL100 (the name of the programming language) in group 2.

When the GEM library is initialized, group information for all modules is automatically registered as shown in FIG. 2. That is, FIG. 2 means that a group targeting all modules has been defined and registered with the group name ALLMOD.

There are multiple modules with the owner name T2620, and if the modules with the same owner name are collected and grouped, and the group name T2620 exists in this group, module 1 with the owner name T2620 is added to the above group. For example, if you enter ADD MO1, OWNER=T2620 as an ADD control statement,
Group information is registered in the group definition management block of the GEM library 1 as shown in FIG.

The group definition information list output function can be used by inputting a new control statement, for example LISTG.Group name Group attribute ALLMOD All modules GROUP1 Module name Any of the modules MO1, MO2, MO3 T2620 List up like a T2620 module.

The group definition information deletion function uses new control statements,
For example, delete the group name specified by DEL GROUP or the definition information of all group names.

The control information includes information such as the fact that this block is a group definition management block and the size of the block.

FIG. 4 shows an overview of group definitions regarding the segmented data set. Conventionally, a partitioned data set consists of a data set name and a member, but this is divided into data sets as shown in Figure 4.
It consists of a set name, group name, and members. Therefore, in the case of Figure 4, if you want to refer to and update member names A, B, and C in screen editing, for example, if you specify the data set name and group name "1," A, B, and C will be displayed on the screen. B and C can be treated as if they were one member.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the group definition information and group information of a data set are registered on the data set, so it is not necessary to perform group definition work for each job step. This also makes data sets easier to use and improves operability. Furthermore, grouping multiple members of a partitioned data set allows all grouped members to be referenced and updated in a single call.
In this case, although a command for controlling switching of members in a group is required, it can be essentially the same as the command for switching members, thereby improving the operability of the segmented data set.

[Brief explanation of drawings]

Figure 1 shows the registration status of specified group definition information, Figure 2 shows the registration status of group information at the time of GEM library initialization, and Figure 3 shows the registration status of group information at the time of module registration. The figure shown in FIG. 4 is a diagram showing the group registration status of members of the segmented data set. 1...GEM library (processing target data set), 2...Divided data set, 3...Group name, 4...Member.
