NAME       : HCPCRWBK
 DESCRIPTION: CHANNEL REPORT WORD BLOCK
 DSECT      : CRWBK
 FUNCTION   : THE CRWBK IS A QUEUE ELEMENT ON THE QUEUE OF PENDING
              CHANNEL REPORT WORDS AWAITING PRESENTATION (VIA A
              MACHINE CHECK INTERRUPTION) TO THE VIRTUAL MACHINE.
 LOCATED BY : CHCIORW - ANCHOR OF QUEUE IN CHCBK
              MCVCRWS - ANCHOR OF QUEUE IN MCVBK
              CRWNEXT - FORWARD POINTER IN PRECEEDING QUEUE ELEMENT
 CREATED BY : HCPVDB - WHEN A DEVICE IS DEFINED FOR A VIRTUAL ESA
              MACHINE
              HCPVOF - DURING SIMULATION OF A RCHP INSTRUCTION
              HCPRFC - TO PASS ON A CRW FOR A DEDICATED DEVICE TO
              CONCERNED VIRTUAL MACHINE
 DELETED BY : HCPMCV - WHEN A VIRTUAL MACHINE IS RESET
              - WHEN THE CRW IS STORED IN THE VIRTUAL MACHINE
              DURING SIMULATION OF A MACHINE CHECK INTERRUPT
              HCPVOF - DURING SIMULATION OF A STCRW INSTRUCTION
 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 LGRCRWBK 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.
