Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.2 compiling     *
  *                 and running programs that contain            *
  *                 computations that could produce a negative   *
  *                 result, where the senders and receiver are   *
  *                 at least 10 digits in length, and the        *
  *                 receiver is unsigned, and either specified   *
  *                 as COMP-5 or as BINARY/COMP/COMP-4 with      *
  *                 compiler option TRUNC(BIN) in effect.        *
  ****************************************************************
  * PROBLEM DESCRIPTION: Incorrect results at runtime/migration  *
  *                      problem: A negative result is not       *
  *                      converted to positive when being        *
  *                      stored to a 64-bit unsigned binary      *
  *                      receiver.                               *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The compiler was incorrectly determining that the sign
  correction to force a positive sign was unnecessary.
  

Problem conclusion

• The compiler was fixed to stop removing the sign correction.
  This behavior is now compatible with pre-COBOL V5 compilers.
  

Temporary fix
