Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL for z/OS V4.1 or   *
  *                 V4.2 compiling with the OPTIMIZE and LIST    *
  *                 compiler options after installing the PTF    *
  *                 (UK98159 or UK98160) for APAR PM96837.       *
  *                                                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Optimizer trace messages, for example:  *
  *                        ==OPT==> UNDERLIMIT VALUE NUMBER      *
  *                                 COUNTER ZEROED               *
  *                      are inserted into the pseudo-assembler  *
  *                      listing generated by the LIST option.   *
  *                      Such trace messages should appear only  *
  *                      if an internal debugging control        *
  *                      statement is specified, but some        *
  *                      messages were always being emitted.     *
  *                                                              *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  *                                                              *
  ****************************************************************
  Optimizer trace messages should be conditional on the presence
  of an internal debugging control statement, but some messages
  were emitted even when this statement was not specified.
  

Problem conclusion

• The optimizer was changed to make all trace messages conditional
  on the presence of the appropriate debugging control statement.
