  Forward fit V2R1 APAR into new V2R2 HPPC version.
  
  The HIALCBYT field in the HISTORY data set has 4 byte length and
  a value represents a database data set size with the following
  encoding scheme -
  
  (1) When a database data set size is less than 4,294,967,296
      (4G) bytes, the size is stored as an unsigned even binary
      value.
  (2) When a size equals or is larger than 4,294,967,296 (4G)
      bytes, an unsigned odd value:
        (actual data set size - 4G) + 1
      is stored.
  
  When a size is larger than 8,589,934,590 (8G-2) bytes, the
  size cannot be represented by this scheme. This results in HDPC
  storing an incorrect value to HIALCBYT.
  
  The new 8 byte binary field HIALCBYD is added to DBDS record in
  HISTORY data set. The field resides in the DBDS statistics
  record 2 which is the same record the HIALCBYT field resides in.
  HDPC will maintain the both fields but when the total size of
  the database data set exceeds 8,589,934,590 byte, HDPC will
  store X'FFFFFFFF' into HIALCBYT in order to minimize the impact
  on the existing user applications.
  The new layout of the record can be referred in FABGHIR DSECT
  macro provided by this APAR.
