  * USERS AFFECTED: Users of Enterprise COBOL V6.3 compiling     *
  *                 and running programs containing              *
  *                 alphanumeric or utf-8 comparisons between    *
  *                 two dynamic-length elementary items using    *
  *                 the EQUAL, NOT EQUAL, GREATER THAN,          *
  *                 GREATER THAN OR EQUAL, LESS THAN, or         *

  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The compiler was generating code for comparing two dynamic-
  length elementary items that was incorrect.
  

Problem conclusion

• The compiler was changed to generate code for comparing two
  dynamic-length elementary items that is consistent with
  comparing fixed-length items, and according to the COBOL
  standard.
