PWIBK Prolog

 NAME       : HCPPWIBK
 DESCRIPTION: PGMBK Walker Interface Block
 DSECT      : PWIBK
 FUNCTION   : Contains a parameter list to pass to HCPRLTPW
              via HCPHDITR, for the purposes of relocating a
              guest.  It is also then subsequently passed
              amongst some lowel-level routines too.
 LOCATED BY : ITRBK field ITRTROPT in HCPRLS and HCPRLT
              PSQBK field PSQPWIBK
              PODBK field PODPWI
 CREATED BY : HCPRLS
 DELETED BY : HCPRLS
 SERIALIZED : Local task serialization (only the owning task has
              the address of the corresponding PWIBK).
 RELOCATION CONSIDERATIONS : None
 COMMENTS   : Used to pass input parameters to HCPRLTPW via
              HCPHDITR.  Used as a common mapping for the parm
              list between HCPRLS and HCPRLT.  It is also used to
              then pass those same parameters amongst some lower-
              level routines as well.
