 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 LGRIORBK 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.

Presimulation backs out for SNID and RSTA. 00001 - A SNID or RSTA was first in the channel program and CCW translation found that presimulation is needed. 01000 - An SMR CCW was first in the chain. If the second CCW is a SPID, presimulation is needed. If the second CCW is a SNID or RSTA, presimulation should back out. 01001 - A SNID or RSTA followed a SMR and CCW translation found that presimulation is needed. 1x00x - Presimulation determined real IO is needed. CCW translation should translate the PGID CCW instead of redriving it. xx01x - Command reject any CCW, including PGID ones. This state is entered after handling a valid PGID CCW other than RSTA. 0x10x - Command reject PGID CCWs.
