     NAME       : HCPSPFBK
     DESCRIPTION: SPOOL FILE DESCRIPTOR (OR CONTROL) BLOCK
     DSECT      : SPFBK
     FUNCTION   : TO CONTAIN SPOOL FILE CHARACTERISTICS, SUCH AS
                  CLASS, DISTRIBUTION CODE, SPOOLID, ETC.
     LOCATED BY : (1)  ROUTINES:
                  HCPSCSGN - WILL RETURN THE ADDRESS OF THE NEXT SPFBK
                  ON THE QUEUE(S) SPECIFIED IN THE CALLERS
                  R1.
                  HCPSCSNM - WILL RETURN THE ADDRESS OF THE NEXT SPFBK
                  WITH THE SPECIFIED FILENAME/FILETYPE ON
                  THE QUEUE(S) SPECIFIED BY THE CALLERS R1.
                  HCPSCSPF - WILL RETURN THE ADDRESS OF THE SPFBK FOR
                  THE SPOOLID SPECIFIED IN THE CALLERS R1.
                  (2)  FIELDS:
                  SPFPNT   - POINTS  TO THE  NEXT SPFBK ON THE QUEUE.
                  IF SPFPNT IS ZERO, IT IS THE LAST FILE.
                  SYSOUTQ  - Points to the first SPFBK on the
                  output queue.  The first word in the
                  SPFBK points to the next SPFBK.  If
                  that field is zero, it is the last
                  file on the output queue.  The output
                  queue consists of printer and punch
                  files.
                  SYSINQ   - Points to the first SPFBK on the
                  input queue.  The first word in the
                  SPFBK points to the next SPFBK.  If
                  that field is zero, it is the last
                  file on the input queue.  The input
                  queue consists of reader files.
                  SYSDATAQ - Points to the first SPFBK on the
                  system data queue.  The first word in
                  the SPFBK points to the next SPFBK.
                  If that field is zero, it is the last
                  file on the system data queue.  The
                  system data queue consists of
                  NSS/DCSS, IMG, UCR, and NLS files.
                  NOTES      :  The SPFBK is also checkpointed in the SPMBKS
                  for the corresponding spoolid.
     CREATED BY : HCPDMQSD - WHEN A CP ABEND DUMP READER FILE IS
                  OPENED
                  HCPSDFON - WHEN A NEW SYSTEM DATA FILE IS CREATED
                  HCPSFROP - WHEN A  SPOOL  FILE  IS CREATED BY A REAL
                  READER
                  HCPSFVOP - WHEN A SPOOL FILE IS CREATED ON A VIRTUAL
                  PRINTER OR CARD PUNCH OR A CP ABEND  DUMP
                  FILE IS OPEN
                  HCPSPZRI - When creating a spool file from a
                  tape via the SPXTAPE command
                  HCPVDUMP - WHEN A VMDUMP READER SPOOL FILE
                  IS OPENED
                  HCPWRSST - WHEN THE SYSTEM IS WARM STARTED,
                  HCPWRS RECREATES THE SPFBK'S FOR ALL
                  SPOOL FILES THAT EXISTED WHEN THE
                  SYSTEM WAS BROUGHT DOWN
     DELETED BY : HCPSFSON - IF THERE IS NO DASD OR SYSTEM VIRTUAL
                  SPACE WHEN A  SPOOL FILE IS BEING CREATED
                  HCPSFRDL - WHEN A  SPOOL FILE  IS TO BE DELETED FROM
                  THE SYSTEM
                  HCPSPORR - When end of command for SPXTAPE SCAN.
                  HCPSPQCT - When end of file for SPXTAPE SCAN.
                  HCPSPZRI - When file being loaded from tape
                  via the SPXTAPE LOAD command does
                  not match criteria or has an error
                  condition.
                  HCPWRSST - WHEN THE SYSTEM IS WARM STARTED,
                  HCPWRS CHECKS TO SEE IF A SPOOL FILE
                  CONTAINED ANY DATA. IF IT DIDN'T, IT
                  DELETES THE SPFBK
     RELOCATION CONSIDERATIONS : None
     NOTES      : When adding new characteristics to the spool file,
                  check if the new characteristics need to be saved
                  when dumping and loading from tape (i.e. HCPSXS,
                  HCPSPX, HCPSPZ) and when checking for duplicate files
                  (HCPSPK).
