 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
 RELOCATION CONSIDERATIONS : None
 HISTORY    : This control block was created with @S712158.
