SNTBK Prolog

 NAME       : HCPSNTBK
 DESCRIPTION: System Name Table Block
 DSECT      : SNTBK
 FUNCTION   : This block is used to keep track of a system data
              file that is brought into the system.
 LOCATED BY : The pointer to this chain of blocks is located in
              HCPNSU, using NSUNSYAN for NSSs, NSUNSGAN for
              DCSSs, NSUIMGAN for images, and NSUNLSAN for
              NLS files.
              - In HCPSHRBK, pointer SHRSNTPT will point to the
              associated HCPSNTBK.
              Pointer SHRLSSA will point to the segment space
              through which the shared segment was loaded.
              - In HCPPGMBK, using the PGMVM pointer will point to the
              associated HCPSNTBK.
              - SNTFWDPT will point to the next HCPSNTBK in the chain.
              - The end of chain is located when the SNTFWDPT equals
              the address of NSUNSYAN, NSUNSGAN OR NSUIMGAN.
              - In HCPIMGBK, IMGSNTBK will point to the
              associated HCPSNTBK.
 CREATED BY : HCPNSL when loading the NSS or DCSS for the first
              time.
              - HCPNSD will build this block for the duration of the
              processing of the DEFSEG and DEFSYS commands.
              - HCPNSS will build this block for the duration of the
              processing of the SAVESEG and SAVESYS commands.
              - HCPNSI will build this block for the duration
              of processing of the diagnose X'74' instruction
              to save or load an image, and the diagnose
              X'CC' instruction to create an NLS message
              repository.
              - HCPNSR will build this block when opening an
              image library or NLS message repository file.
 DELETED BY : HCPNSP will delete this block when the count fields
              of an NSS or DCSS go to zero. The fields are
              SNTUSRSH and SNTUSREX.
              - HCPNSD will delete this block after processing
              the DEFSEG or DEFSYS command.
              - HCPNSS will delete this block after processing the
              SAVESEG or SAVESYS command.
              - HCPNSI will delete this block after processing
              diagnose X'74' to save or load an image, or
              diagnose X'CC' to create an NLS message
              repository.
              - HCPNSR will delete this block when closing the
              image library or NLS message repository.
 COMMENTS   :
              - The size of this block is 4K, a page of storage.
              - *****NOTE***** This control block maps the
              descriptor page for certain system data files.
              Extreme care must be exercised when updating this
              block, to avoid causing files created prior to
              the update to break. Changes must be made in an
              upward-compatible way

     The following are the flags that indicate status.
     The field below, SNTENVFG, is kept in this block for compatibility
     only. It has been superceded by SNTMENVF. The values in this field
     should not be used in code other than the compatibility code currently
     referencing it.
     This field is defined to contain the virtual machine mode in which the
     NSS was saved. It therefore can have only one value.
     The field that supercedes this one, SNTMENVF, was defined as indicating
     which virtual machine modes were specified on the DEFSYS command. It
     now is defined as indicating in which mode(s) the NSS can be IPLed.

                                        Note that this bit is only valid
                                        for DCSS and segment space
                                        SNTBKs.

     SNTBK/SHRBK queue lock (SNTSHRLK)
     Lock type: This is a formal shared or exclusive lock
     Resource serialized: This lock manages the SHRBK queue chained from the
     SNTBK. The lock will be obtained shared when scanning the queue and
     exclusive when adding to, or deleting from, the queue. This lock is
     also used to serialize the following SNTBK 'use-counts': SNTUSRSH,
     SNTUSREX, SNTLODCT. The lock must be obtained exclusive when updating
     these counts.
     Notes : If the Saved Segment SNTBK queue or Named Saved System SNTBK
     queue lock is held exclusively then the SNTBK/SHRBK lock does not need
     to be obtained to add/ remove a SHRBK or increment/decrement the
     'use-counts'.
