Chapter 3 Managing IMS Data Definitions : Task F: Select IMS Segments

Task F: Select IMS Segments
After you select an IMS database, you must select segments from it. To do this, you must determine the access path required to retrieve the data you need. Refer to Effects of Segment Selection for more information.
The root segment is automatically included in the access path and already appears in the Segment Name field on the IMS Table Definition screen with a level of 0. Additional segments that you select must be along one access path (that is, you can choose only one segment from each level, as long as you also choose its parent).
Selecting Additional Segments
To select additional segments, complete the following steps:
1.
A screen similar to the one shown below appears.

 
Use ’S’ to select a child segment:
Level Segment Name

1 _ ADDRESS
PFKEYS: 3=END 12=END ENTER=SELECT

 
2.
A screen similar to the one shown below appears with the selected child segment listed under the parent segment.
