     NAME       : HCPMCVBK
     DESCRIPTION: VIRTUAL MACHINE CHECK BLOCK
     DSECT      : MCVBK
     FUNCTION   : HCPMCVBK MAINTAINS THE DESCRIPTION OF A MACHINE CHECK
                  INCIDENT BEFORE THE INTERRUPT IS REFLECTED TO THE GUEST.
                  THERE ARE THREE TYPES OF MCVBKS MAINTAINED IN THE SYSTEM.
                  MCVBK (DYNAMICALLY ALLOCATED MCVBK)
                  STORAGE  IS OBTAINED  FOR  A DYNAMICALLY  ALLOCATED
                  MCVBK WHEN REQUIRED.  IT HAS  TWO USES. THE CONTROL
                  PROGRAM BUILDS  MCVBKS WHEN  SOME SYSTEM  INCIDENT,
                  THAT  IS  NOT  A  REAL  MACHINE  CHECK,  IS  TO  BE
                  REFLECTED TO THE  GUEST AS A MACHINE  CHECK.  IT IS
                  ALSO USED  TO MAKE  COPIES OF  MCVBKS TO  ALLOW THE
                  REFLECTION OF  MACHINE CHECKS TO  A GUEST  TO OCURR
                  ASYNCHRONOUSLY WITH OTHER CP FUNCTION.
                  MCVBK (CPU MCVBK)
                  WE REFER TO  THIS MCVBK AS THE  'CPU MCVBK' BECAUSE
                  EACH CPU OWNS ONE, AND  ALSO TO DISTINGUISH IT FROM
                  THE  'SYSTEM  TERMINATION MCVBK'  DESCRIBED  BELOW.
                  THE CPU MCVBK  CONTAINS A DESCRIPTION OF A REAL ERROR
                  INCIDENT  (IF ANY)  CURRENTLY IN  PROGRESS ON  THIS
                  CPU.  IT  IS NEEDED MAINLY  FOR THE BENEFIT  OF THE
                  VIRTUAL  SIDE  OF  THE SYSTEM  (HCPGMCMC)  SO  THAT
                  MACHINE CHECKS CAN BE  REFLECTED TO GUESTS.  HCPMCH
                  CALLS HCPGMCMC AND PASSES  THE CPU MCVBK CONTAINING
                  THE DESCRIPTION OF THE INCIDENT.   THE CPU MCVBK IS
                  ANCHORED IN THE PREFIX PAGE BY 'PFXMCVBK'.
                  DATA IS  PLACED IN  THE MCVBK  AT THE  START OF  AN
                  INCIDENT AND IS CLEARED AT  THE END OF THE INCIDENT
                  SO  THAT THE  BLOCK REMAINS  EMPTY  UNTIL THE  NEXT
                  INCIDENT.
                  MCVBK (SYSTEM TERMINATION MCVBK)
                  THERE ARE ALSO 'SYSTEM TERMINATION' MCVBKS (THERE
                  ARE 32 IN THE SYSTEM).  THEY ARE PERMANENTLY ALLO-
                  CATED IN A WORK AREA HCPWRKMV AND REMAIN INTACT
                  ACROSS A SYSTEM TERMINATION AND SOFTWARE-RE-IPL.
                  THEY ARE USED TO PASS REAL MACHINE CHECK (OR OTHER
                  SYSTEM INCIDENT) DESCRIPTIONS TO INDIVIDUAL VMDBKS
                  IN THE V=R GUEST CONFIGURATION SO THAT MACHINE
                  CHECKS MAY BY REFLECTED TO THE V=R GUEST AFTER THE
                  SYSTEM HAS RE-IPL'D.
                  AT SYSTEM  TERMINATION TIME, HCPWRP  CALLS HCPMCWMD.
                  HCPMCWMD GATHERS INFORMATION FROM THE INDIVIDUAL
                  CPU MCVBK'S (AND OTHER SOURCES) AND PLACE IT IN THE
                  SYSTEM TERMINATION MCVBKS (ONE SYSTEM TERMINATION
                  MCVBK IS USED TO RECORD THE STATE OF ONE REAL CPU).
                  AFTER THE SOFTWARE-RE-IPL THESE MCVBKS ARE PASSED
                  TO HCPGMCGS SO THAT A MACHINE CHECK CAN BE
                  REFLECTED TO THE V=R GUEST IF APPROPRIATE.
