How to Begin Using the Product › Purpose of These Lessons › Allocate a Test Data Set

Allocate a Test Data Set

Begin at your ISPF Primary Option Menu. ISPF is the main user interface for your z/OS operating system.

This panel is the origination point from which you enter all ISPF facilities and functions.

To allocate a test data set

1. Enter 3.2 in the Option field.

   The Data Set Utility panel is displayed. Use this panel to enter the name of a data set that you can use for testing rules. Your user ID, with TEST, and RULES, makes a good name for such a data set.

2. Fill in the Data Set Utility panel with the following suggested entries.
   • Enter an A in the Option field.
   • Enter your user ID in the Project field.
   • Enter TEST in the Group field.
   • Enter RULES in the Type field.

   The Data Set Utility panel will look similar to that shown here:
