User-defined variables and variable tables

Beside the supplied variables, you can define variables in a variable table by using the JCL VARIABLE panel.

Select option 9 (JCLVAR) from the MAINTAINING DATABASES panel, or enter the fast path 1.9 from the main menu. You see the MAINTAINING JCL VARIABLE TABLES panel, shown in Figure 1.

Figure 1. EQQJVMAP - Maintaining JCL Variable Tables

EQQJVMAP ----------- MAINTAINING JCL VARIABLE TABLES ----------------------
Option ===>

Select one of the following:


1 BROWSE          - Browse variable tables

2 MODIFY          - Create a new JCL variable table or modify,
                    copy, browse or delete an existing variable table

3 PRINT           - Print variable tables

(MODIFY). You then see a filter panel that lets you select which JCL variable tables you want to look at. If you leave all the fields blank when you press Enter, you see a list of all the JCL variable tables defined to your IBM Z Workload Scheduler system. See Figure 2.

Command ===>

Enter the CREATE command above to create a new JCL variable table
or enter any of the following row commands:
M - Modify, C - Copy, D - Delete, B - Browse


Row Variable         Owner             Table                    Last updated
cmd Table            Id                Description              by

 _  INVOICE2         OPSMGR            INVOICES REGION EAST     XCALLIN
 ******************************* BOTTOM OF DATA ********************************

From this panel, you can copy, modify, browse, delete, and create a variable table. Enter the CREATE command to display the CREATING A JCL VARIABLE TABLE panel, where you are prompted for a table name, the names of the variables you want to create, and other details. See Figure 3 for an example of variable creation.

****************************** BOTTOM OF DATA  *********************************

The SETUP option specifies when the variable is substituted. See When variables are substituted for more information.

You can specify the variable-substitution exit, rather than IBM Z Workload Scheduler should substitute the variable. For more details about this exit, see Variable-substitution exit (on JCL or job definition variable).

When you select a variable from panel EQQJVVCL, you can make detailed modifications to it using this panel:

Command ===>

Enter/Change data below, or DEP command to create/modify dependency,
Enter VER command to define verification rules.

Variable table        :MONTHLY          Monthly variables
Variable name         :PXM0001

DESCRIPTION        ===> ____________________

SUBSTITUTION EXIT  ===> ________     A load module name
VALUE REQUIRED     ===> _            Y - Yes, N - No
DEFAULT POSITION   ===> __           01 - 80  A position in a JCL

DIALOG TEXT        ===> ___________________________________________________

                        ___________________________________________________
                        ___________________________________________________

Set the UPPER CASE field to Y, if you want lower case characters of the DEFAULT VALUE field to be translated to upper case.

The VALUE REQUIRED option specifies whether the variable can be blank. If you set this field to Y, the value cannot be assigned a blank value.

When you have selected and defined a variable, you can specify:
- Dependencies on the variable (see Making one variable dependent on another)
- Validation criteria for the variable (see Variable validation)
by entering the DEP or VER primary command.
