 NAME       : HCPRTVBK
 DESCRIPTION: CP Program Function Key Retrieve Block
 DSECT      : RTVBK
 FUNCTION   : The RTVBK contains information used to
              handle PFKey RETRIEVE requests
 LOCATED BY : HCPPFUNC field PFUNRTV
 CREATED BY : HCPPFK
 DELETED BY : HCPPFK
 RELOCATION CONSIDERATIONS : This control block is relocated as part of a live
              guest relocation (LGR).  The bits and fields that
              need to be relocated are defined in the
              corresponding LGRRTVBK COPY file.  Whenever changes
              are made to this control block, consideration must
              be given to any effects these changes will have on
              a relocation.  If any new fields or bits are
              defined, they may need to be relocated.  If
              existing bits or fields are changed, corresponding
              modifications may be required in the LGR version of
              this control block.  Consider also the effects of
              these changes on a relocation involving a back-level
              release of CP.
