Connecting Records to Chained Sets

Operations Performed

CA IDMS/DB performs the following operations to connect a record (that has previously been stored) to a chained set:

• Updates the prefix of the record being connected to reflect the record's next, prior, and owner (as applicable) pointers in the set
• Updates pointers in all other records affected by the new set connections

In the following example, EMPLOYEE 19 and EMPLOYEE 23 have been stored on pages 7023 and 7026, respectively. Connecting each to DEPT 3100 as members of the DEPT-EMPLOYEE set affects the DEPT 3100 record on page 7126. Its prefix must be updated to point to the next and prior members of the set.
