Set up a Segment Search Argument (SSA) for DEMOHDRS

The IMS Database Editor can store the SSAs that you create for up to the last ten databases edited.

1. Click on the IMS Database Editor toolbar to move to the start of the database.

   This positions you at the top of the first DEMOHDRS segment occurrence which is the Table of Software Developers.

   On the SSA List, the SSA column for the DEMOHDRS segment shows None, indicating that DEMOHDRS has no SSAs.

2. On the SSA list, double-click the DEMOHDRS segment.
3. On the Define SSA dialog box, click Unqualified SSA for DEMOHDRS, and then click OK.

   On the SSA list, the SSA column changes to DEMOHDRS*-.

4. Click on the IMS Database Editor toolbar.

   Because you just defined an unqualified SSA, Get Next With Hold returns another DEMOHDRS segment rather than the next DEMOELES segment.

5. Click on the IMS Database Editor toolbar two more times.

   As there are no more DEMOHDRS segments, a message prompt appears, indicating that you have reached the end of database.

6. Click Yes to reset to the start of the database.
7. On the SSA list, double-click on DEMOHDRS.
8. On the Define SSA dialog box, click No SSA and click OK.

   This removes the unqualified SSA from DEMOHDRS. On the SSA list, the SSA column now shows None.

This completes the tutorial.
