Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V5.1 compiling     *
  *                 large programs with many Working-Storage     *
  *                 data items that are set and then not         *
  *                 changed and using compiler options OPT(1)    *
  *                 or OPT(2).                                   *

  * PROBLEM DESCRIPTION: Compiler Performance:  The optimizer    *
  *                      takes a long time to optimize such      *

  ****************************************************************
  Propagating 'read only' or 'constant' Working-storage data
  items to their uses would take a long time if the list of read
  only items is large.
  

Problem conclusion

• The optimizer logic for propagating 'read only' working-storage
  data items to their uses was improved to run faster.
  

Temporary fix
