Redefinitions Without Record IDs in COBOL Copybooks
Redefinitions Without Record IDs in COBOL Copybooks
A COBOL copybook might include REDEFINE statements but no RID field. In this case, the createdatamaps utility defines one record and one table for each possible combination of redefined fields, up to the maximum number that the maxRedefines element specifies. By default, maxRedefines specifies 1. For IMS data maps, the default of 1 always applies.
If a copybook for a sequential or VSAM data map contains multiple 01-level records, MaxRedefines applies to each 01-level record in the copybook.
After you create the data map, you can edit the data map in the PowerExchange Navigator as needed to delete unwanted records and tables.
