     NAME       : HCPSI1GB
     DESCRIPTION: SIE STATE DESCRIPTION (Format 1)
     DSECT      : SIEBK
     Function   :
                  This control block describes a guest virtual
                  machine to the emulation hardware. It defines
                  a SIE format-1 state description, which is the
                  operand of a host SIE instruction when CP is
                  running as an ESA/390 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.
