     NAME       : LGRPPRBK
     DESCRIPTION: Relocation mapping for post-processing
     DSECT      : $PPRBK
     FUNCTION   : LGRPPRBK acts as an anchor for formatted control
                  blocks that are sent to the destination system
                  during the post-processing phase of guest relocation
     LOCATED BY : This is a mapping of the RDODATA area within the
                  RDOBK during guest relocation.
     RELOCATION CONSIDERATIONS : None
