 NAME       : LGRPROBK
 DESCRIPTION: Relocation mapping for HCPPROBK
 DSECT      : $PROBK
 FUNCTION   : LGRPROBK describes those fields of the PROBK 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 HCPPROBK 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 PROBK flags that are subject to
               relocation. These bits are defined sequentially,
               regardless of how they are defined in HCPPROBK.
               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.

      Data:    Contains all HCPPROBK data that is subject to
               relocation, except for flag bits, which are
               handled separately.
               All fields are defined as XLnn to avoid alignment
               warnings and to pack the data efficiently.

      Most of the fields listed here are copied as-is to the
      destination system, but some require special processing.
      Such fields are marked with '**'.
