  This APAR fixes the following existing problems of DBD/PSB/ACB
  Reversal utility decode function and DBD/PSB/ACB Compare utility
  source level compare report.
  
   1. EXIT= operand on SEGM statement of SHISAM DBD or ACB is not
      decoded/compared.
  
   2. When a 255 bytes long character is specified as VERSION=
      operand, unnecessary MSGFAN0030W is issued when decoding/
      comparing DBD or ACB and the decode function ends with a
      return code of 04.
  
   3. When decoding with COMPRESS=YES specified, if some blank
      characters are included in the value specified as VERSION=
      or REMARKS= operand, the value is decoded with incorrectly
      compressed.
      If some blank lines are included in the value, ABEND0C4
      occurs.
  
   4. PAIR= operand and RULES= operand of LCHILD statement of DBD
      or ACB is not decoded/compared if the database has
      bidirectional physical paired logical relationship.
  
   5. REMARKS= operand after PSELOPT= operand on XDFLD statement
      of DEDB DBD or ACB is incorrectly decoded/compared.
  
   6. When (segment, DBLE) is specified in the PARENT= operand on
      SEGM statement of HISAM DBD, the DBLE parameter is
      unnecessary but decoded/compared.
  

Problem conclusion

• The following modules have been changed to fix the above
  problems:
  
   - FABNDBD0
   - FABNLCH0
   - FABNDCTL
   - FABNPCTL
  
  Additionally, FABLACBD module is changed not to compare
  unused field of ACB. This does not effect existing function.
