How the createdatamaps Utility Creates Records for Redefined Fields and Groups

How the createdatamaps Utility Creates Records for Redefined Fields and Groups

The createdatamaps utility builds an internal model that represents all of the combinations of redefined fields and groups.
For example, consider the following record from a COBOL copybook:
01 MASTER-REC. 05 MASTER-DATE. 07 some fields 05 MASTER-DOB REDFEINES MASTER-DATE. 07 some fields 05 OTHER-DATE. 07 some fields 05 OTHER-DOB REDFEINES OTHER-DATE. 07 some fields
The utility creates an internal model with four layouts. the layouts correspond to the following combinations of fields:
  • MASTER-DATE / OTHER-DATE
  • MASTER-DATE / OTHER-DOB
  • MASTER-DOB / OTHER-DATE
  • MASTER-DOB / OTHER-DOB
The utility creates a record and table for each of the first
maxRedefines
layouts in the model. For more information, see Use of the maxRedefines Element to Limit the Number of Records.
