FSBK Prolog

 Name       : HCPFSBK
 Description: CP File Status Block
 DSECT      : FSBK
 Function   : The FSBK contains information about a single
              file on the mini-disk
 Located by : FSBK.FSHFSBR(i)
              OFBK.OFBFSB
 Created by : HCPZIA
 Deleted by : HCPZIA
              HCPZIR
 Comments   : Individual FSBK storage areas are actually contiguous
              sections in full pages that are pointed to by FSHBKs.
              Individual FSBKs are never allocated by HCPGETST and
              never released by HCPRELST.
