     NAME       : HCPDFIR
     DESCRIPTION: DUMP FILE INFORMATION RECORD
     DSECT      : DFIR
     FUNCTION   : HCPDFIR contains vital system register and storage
                  location values for a dump of a system.
                  HCPDFIR is the ESA/390 snapshot of this information
                  and HCPDFIZ is the zArch snapshot of the same
                  information.  The HCPDFIZ DSECT is included in
                  this file.
     LOCATED BY : The DFIR starts at the third record of a system
                  abend dump to tape or DASD, of a standalone dump to
                  tape, or of an VMDUMP SPOOL file.
     CREATED BY : HCPDMP (SYSTEM ABEND DUMP PROCESSOR) DURING A SYSTEM
                  ABEND DUMP
                  HCPEDM (DUMP PROCESSOR) WHEN PROCESSING A SYSTEM ABEND
                  OR STANDALONE DUMP
                  HCPSAD (STANDALONE DUMP PROCESSOR) DURING A STANDALONE
                  DUMP
                  HCPVDU (VIRTUAL MACHINE DUMP PROCESSOR) DURING A VIRTUAL
                  MACHINE DUMP
     DELETED BY : NOT APPLICABLE
     COMMENTS   : The HCPDFIR is used by HCPEDM (DUMPLOAD) to process a
                  dump from tape or dasd.
                  The DFIR is 5 4k bytes in length and can contain
                  information for up to 63 processors.
                  The DFIZ is 9 4k bytes in length and can contain
                  information for up to 63 processors.
                  HCPDMP builds the DFIR in the work pages HCPWRKA1 to
                  HCPWRKA5.  HCPDMP builds the DFIZ in the work pages
                  HCPWRKA1 to HCPWRKA9.
                  HCPVDU builds the DFIR in the work pages HCPWRKA1 to
                  HCPWRKA5.  HCPVDU builds the DFIZ in the work pages
                  HCPWRKA1 to HCPWRKA9.
                  The displacement of DFIDVF cannot change because
                  DFIDVF is used by DVF to determine if the dump
                  release matches the DUMPSCAN release.
                  The offset and content of some fields in the DFIR
                  DSECT must precisely match the offset and content of
                  equivalent fields in the DFIZ DSECT.  These fields
                  are clearly marked.  DUMPLOAD depends on this fact.

                 - The DFIZ is bigger because lots of fields are
                   bigger.  The DFIZ takes up 9 pages (8 full pages
                   and 1 partial page).
                 - The offset and content of some fields in the DFIR
                   DSECT must precisely match the offset and content
                   of equivalent fields in the DFIZ DSECT.  These

                   that other fields will appear in both the DFIR
                   and DFIZ DSECTs.
                 - The data for the non-failing CPU's is defined
                   with a separate DSECT (DFIZCPU).
                 - HCPDMP builds the DFIZ in the work pages HCPWRKA1
                   through HCPWRKA9.
                 DFIZ Revision 2 Format - See DFIZFMT byte.
                   In this release, the DFIZ will always be in
                   Revision 2 format.  Change from Revision 1 are:
                   1. Added DFIZFR2 definition to DFIZFMT byte.
                   2. DFIZINFO defined - This field indicates the
                      "Format of the Dump".  The various dump
                      generating programs will produce these dump
                      formats based on the environment that is
                      present at the time of the dump.
                   3. DFIZDVF no longer defined.  This field was not
                      being used because DVF does not support dumps
                      with a DFIZ.
                   4. DFIZSYSR and DFIZSTOR fields renamed.
                      Equivalent data is now stored in the ASIBK.
                      These old fields are left as "Reserved" and
                      with different labels for use by VM DUMP TOOL.
