Enterprise Developer supports two segment layout types:
- Default
- You can define one default segment layout for each IMS segment; however it is not mandatory. A default segment layout formats data that does not meet the conditions specified by any conditional segment layouts you have created for that segment type.
- Conditional
- You can define one or more conditional segment layouts for each IMS segment. When you create a conditional segment layout, you define a test that applies to one or more fields. To use a conditional segment layout, the data in a segment occurrence must satisfy all the tests defined for that layout.
Note:
- When you initialize a segment occurrence you can choose to specify a segment layout for entering data.
- When you modify data, the IMS Database Editor works out automatically which layouts to use for which occurrences.
