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).
