 NAME       : HCPMWBK
 DESCRIPTION: Multiple address space (MAS) Work area
              BlocK
 DSECT      : MWBK
 FUNCTION   :
              The MWBK is used in multiple address space instruction
              simulation. It is used as a work area by the istru-
              ction simulation routines in preparing updates values
              of the VMDBK fields, affected by the instruction simu-
              lations. It is also used as a shared buffer by the
              simulation routines and some of the services these
              routines invoke.
 Located by : HCPMWPBL builds it and puts its address
              (free storage address) in R10.
              This control block exists for the duration of
              the instruction simulation routines which
              use it and R10 contains always its address.

     Function : The ASTE maps the storage associated with one entry of an
     ASN-Second Table. The entry is used in ASN and AR translation.
     Notes : CR0.15 is the multiple address space control bit. If set the
     ASTE length is 64 bytes; otherwise, the length is 16 bytes. The first
     16 bytes are the same for both formats. The ASTE is always 64 bytes for
