Check, Save, Retrieve, and Clear Variables

Options 9 through 12 on the Installation Variables Management Menu perform the true management of the variables. Each option is invoked from the Installation Variables Management Menu by typing the option number and pressing Enter.

• Option 9—Check Variables. This option performs validity checking on the working copy of the variables. Validity checking can be performed at any time, but the process cannot automatically update any invalid values.
• Option 10—Save Variables. This option saves the working copy of the variables in a member called TILITSAV in the JCL library. That member is stored in the JCL library you referred to on the Set Library Name screen. If it does not already exist, TILITSAV is created automatically when you select this option. It can also be copied from one installation JCL library to another to provide a starting point for future installations.

  Note: When you save variables, the save action overwrites any current values in TILITSAV. If you want to save the existing values in TILITSAV member for use later, you must rename TILITSAV to a new name before saving the new variables.

  To save new variables for subsequent recall, select option 10 on the Installation Variables Management Menu. If you do not explicitly save the new variables, they are automatically saved when the system CLISTs are created.

• Option 11—Retrieve Variables. This option loads previously saved variables, from the permanent storage location, for the current session. You must save variables at least once before you can retrieve them.
• Option 12—Clear Variables. This option deletes current settings in the working copy of the variable table and restores the default settings.
