Tutorial: IMS Segment Layout Editor

Walks you through the process of using the IMS Segment Layout Editor to create default and conditional COBOL layouts for an IMS database.

You can define one default segment layout for each segment type. You can also define one or more conditional segment layouts for the same segment type. The IMS Database Editor uses the default segment layout to format data for those segment occurrences that do not match any of the conditional segment layouts.
