  ****************************************************************
  TRACE IHCUANA1 2020 can be issued when NOREORGV is specified in
  RECON. The TRACE means invalid ILKs. However invalid ILKs do
  not immediately indicate the database failure.
  So code has been changed as follows.
  - A return code of 4 is set instead of a return code of 8
    when invalid ILKs are detected.
  - When the number of invalid ILKs is more than 100, TRACE
    IHCUANA1 2020 is skipped to issue.
  IMS HALDB Toolkit User's Guide has also been changed to add
  user actions when invalid/duplicate ILKs are detected.
  In addition, the following fix has been applied in this APAR.
  - Verify ILK phase is processed even if VERIFYILK(Y) is not
    specified. Code has been changed not to process Verify ILK
    phase when VERIFYILK(Y) is not specified.

Problem conclusion

• Code has been changed to set correct return code and not to
  issue TRACE IHCUANA1 2020 when more than 100 invalid ILKs are
  detected.
