     NAME       : HCPPSFBK
     DESCRIPTION: PURGE SPOOL FILE CONTROL BLOCK
     DSECT      : PSFBK
     FUNCTION   : One PSFBK will reside in a linked list.  This
                  list will keep track of all of the SPOOL files
                  that should be deleted after processing on the
                  file is completed.
     CREATED BY : HCPCSFCX - Process CHANGE and TRANSFER commands
     DELETED BY : HCPSCSPL - Process the PSFBK queue
     HISTORY    : This control block was created with @S712158.
