      FUNCTION =
           Declare a structure for the keypoint list element (KPLE).
           The keypoint list forms part of file control's
           implementation of fuzzy image copy, also known as backup
           while open. One KPLE exists for each keypoint and records
           the start and end times at which tie up records are written.
      LIFETIME =
           The keypoint list elements are created, processed and
           deleted (when they become redundant) by DFHFCBWO. DFHFCBWO
           is called from the file control revovery program DFHFCRC
           following RMKP take keypoint calls from recovery manager.
      LOCATION =
           The KPLE chain is anchored off fc_kple_chain in file
           control static storage.
      STORAGE CLASS =
           KPLEs are getmained from the variable length file control
           subpool above the line.
