     Name       : HCPSCFBK
     Description: System Config File Parsing plist
     DSECT      : SCFBK
     Function   : The SCFBK contains information that describes the
                  result of a record having been parsed by the HCPZPR
                  parser.

     Comments   : Throughout this COPY file, we repeatedly ORG back to
                  SCFMISC.  This action helps reduce the size of the
                  SCFBK.  However, this also places a burden on the
                  programmer.  To ensure that there are no destructive
                  redefinitions that would cause a single configuration
                  file statement to store separate data items into the
                  same location even while using different labels, the
                  programmer should make sure that all fields for a
                  single configuration file statement are in the same
                  redefinition area, or are part of the area defined in
                  the SCFBK prior to SCFMISC.  To aid this effort,
                  comments at the beginning of each redefinition area
                  should indicate which configuration file statements
                  store into the redefinition area.  A configuration
                  file statement should not be listed in more that one
                  redefinition area.
                  As a general practice in this file, one should keep
                  the redefinition areas in alphabetic order based on
                  the configuration file statement type.  If a statement
                  can completely reuse fields within a redefinition area
                  that was already established for another statement,
                  only then would one violate this rule about alpha-
                  betic order.  See the redefinition area for IMBED
                  and TRANSLATE_TABLE for an example of multiple
                  statements using the same redefinition area.
                  If sharing a redefinition area with another statement,
                  additional fields may be defined, as long as the
                  sum of the fields does not exceed the definition of
                  SCFMISC.
                  SCFMISC can be increased as long as the total sum of
                  the SCFBK does not exceed the amount that one can
                  get in a single HCPGETST request.
                  For BLOCKDEF and for BLOCKMAP, no fields may be defined
                  following the redefinitions of SCFMISC.  That means,
                  once we have specified one ORG statement, we have
                  determined the size of the control block.  All further
                  definitions must lie within that size.
                  For BLOCKDEF and for BLOCKMAP, we have placed a few
                  "Reserved" fields.  Their only purpose is to align
                  subsequent fields so that BLOCKMAP pictures will
                  look nice.
