 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).

Live guest relocation eligibility checks use this field to ensure that matching NSS/DCSS exist on the source and destination systems. We ORG over SPFOFORM and SPFCHARS (two otherwise unused fields) instead of creating new ones because the SPXTAPE command already backs up these fields and restores them for us.
