  * USERS AFFECTED: Users of IBM Automatic Binary Optimizer      *
  *                 (ABO) for z/OS, 2.2 Trial.                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: This APAR adds the following new        *
  *                      function from the ABO 2.2 PTF:          *
  *                                                              *
  *                      1) When ABO optimizes input modules     *
  *                      originally compiled at OPT that have    *
  *                      a constant reference outside of the     *
  *                      bounds of WORKING-STORAGE, ABO may      *
  *                      abend with the following message in     *
  *                      the OPTLOG dataset: Assertion failed    *
  *                      at ./BinOptLinkage.cpp:1785. Such a     *
  *                      module may have the following warning   *
  *                      message present in its original         *
  *                      compiler listing: IGYOP3235-W A         *
  *                      reference to "" was found to have a     *
  *                      constant reference-modification start   *
  *                      value that addressed an area outside    *
  *                      of the data item.  The reference was    *
  *                      accepted.                               *

  *                      2) When ABO is generating the listing   *
  *                      transform to a dataset with RECFM=FB,   *
  *                      LRECL=133 as recommended by the User's  *
  *                      guide ABO may generate a long line      *
  *                      (over 133 chars) in the listing         *
  *                      transform file that may cause ABO to    *
  *                      abend with the following message in     *
  *                      the OPTLOG dataset: BOZ1446U: An I/O    *
  *                      error occured while writing the         *
  *                      Listing transform.                      *
  *                                                              *
  *                      3) In rare cases, COBOL-compiled        *
  *                      programs containing CALL statements     *
  *                      with large numbers of parameters may    *
  *                      be optimized incorrectly by ABO,        *
  *                      resulting in incorrect parameters       *
  *                      being passed to the target program.     *
  *                      The problem is most likely to occur     *
  *                      when there are multiple consecutive     *
  *                      CALL statements to the same program     *
  *                      with varying parameters. Symptoms       *
  *                      may be "SQLCODE -310 DECIMAL HOST       *
  *                      VARIABLE OR PARAMETER number CONTAINS   *
