NAME       : HCPVUDBK
 DESCRIPTION: Vestigial User Data Block
 DSECT      : VUDBK
 FUNCTION   : To contain Vestigial User Data (historical data for
              resources owned by the user which have since been
              destroyed).
 LOCATED BY : VMDVUDBK Field of a base VMDBK
 CREATED BY : VUDBKs are dynamically created by HCPASMDS or
              HCPASNRS when destroying an address space.
 DELETED BY : VUDBKs are deleted during log-off processing.
 SERIALIZED : Access to this control block is obtained by acquiring
              the owning user's VUDBK spin lock.
 RELOCATION CONSIDERATIONS : This block is sent to the destination system during a
              relocation. Any changes made to it should be done in a
              compatible manner. Offsets for existing fields should
              not change; any new fields should be added to the end.
              If changes are made to this block, consideration
              should also be given to creating and sending a
              LGRVUDBK COPY file (i.e., a relocation mapping file).
