     NAME       : HCPSI2GB
     DESCRIPTION: SIE STATE DESCRIPTION (Format 2)
     DSECT      : SIEBK
     Function   :
                  This control block describes a guest (virtual
                  machine) to the interpretive-execution facility
                  of the machine (embodied in the SIE instruction).
                  It defines a SIE format-2 state description, which
                  is the operand of a host SIE instruction when CP is
                  running as an ESAME mode host. The SIE state
                  description used by the host control program to run
                  a guest is imbedded in the VMDBK, which is
                  described by HCPVMDBK COPY.
                  The SIE state description is also used by a guest
                  control program operating in ESAME mode to run a
                  virtual guest. In that context, it is the operand
                  of a guest SIE instruction.
                  This control block is defined by processor
                  architecture.

     Comments   :
                  As noted above, VM uses the state description in two
                  contexts:
                  1) It is imbedded within the VMDBK which we use to
                  represent first-level guests (RGuests) when we issue
                  the SIE instruction to run those guests.  In this
                  case, we refer to it as a SIEBK.
                  Some of the comments on fields below apply only to the
                  SIEBKs which are imbedded in RGuest VMDBKs.  Those
                  comments are surrounded by the annotation:
                  [VMDBK only:   ].
                  2) It is an argument of an RGuest's SIE instruction.
                  In this context, it is not associated with a VMDBK --
                  at least, our usage can not depend on such an
                  association, as we are limited to the interface
                  specified by the interpretive-execution architecture.
                  When referring to such a state description, we call it
                  an SI1BK (if the RGuest is in ESA/370 or ESA/390 mode)
                  or an SI2BK (if the RGuest is in ESAME mode).
                  Note that in processing such a state description, we
                  will translate it into a "shadow" state description
                  imbedded in a vSIE VMDBK; we may thereafter refer to
                  it as a SIEBK.  In general, "[VMDBK only:]" comments
                  do not apply to the SIEBKs in vSIE VMDBKs.
