$PPRBK Prolog

 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
