Before you begin: Allocate a partitioned data set for the ACS test cases. The partitioned data set must have a logical record length of 80 or greater and a record format of F or FB. Then, display the ACS Application Selection panel. See Creating ACS routines.

Perform the following steps to create ACS test cases.

1. Select option 4, Test, from the ACS Application Selection panel. This displays the ACS Test Selection panel.

2. Supply values on the ACS Test Selection panel:

   ACS Test Library and ACS Test Member

   These identify the data set and member that contain the test case. You can specify one test case per member.

   Option

   Select option 1, Define, to specify test criteria. This displays the ACS Test Case Define panel.

3. Supply values on the ACS Test Case Define panel, which has multiple pages. On these pages, you can specify test values that correspond to the ACS variables listed in Writing ACS routines.

   On page 3, you can specify values corresponding to the MSxxxx parameters that you expect to be returned from your tape management system through the pre-ACS routine. See Tape management system support for a description of these parameters, and use the documentation provided by your tape management vendor for more specifics.

4. Use the END command to save your test values and return to the ACS Test Selection panel. On the ACS Test Selection panel, you can add more test case members to the same test library, or you can build another test library.
