 NAME       : LGRFINBK
 DESCRIPTION: Relocation mapping for HCPFINBK
 DSECT      : $FINBK
 FUNCTION   : LGRFINBK describes those fields of the FINBK that
              will be migrated to the destination system during
              guest relocation.
 LOCATED BY : This is a mapping of the RDODATA area within the
              RDOBK during guest relocation.
 RELOCATION CONSIDERATIONS : This control block is used during live guest
              relocation.  It is used to relocate a control block
              defined in a corresponding HCP COPY file.  Any
              fields or bits defined in HCPFINBK which are
              required on the destination system must be defined
              here, and code must be added to migrate the field
              or bit during a relocation.

      Bit map: Contains the FINBK flags that are subject to
               relocation. These bits are defined sequentially,
               regardless of how they are defined in HCPFINBK.
               This yields a consistent mapping that ensures
               compatibility when a guest is relocated between
               systems at differing service levels.
               Names in the comments column indicate the control
               block byte which contains the flag. This name is
               subject to change if the flag definition changes.

               All fields are defined as XLnn to avoid alignment
               warnings and to pack the data efficiently.
