Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.1 compiling     *
  *                 programs that MOVE data from numeric-edited  *
  *                 data items to unsigned numeric USAGE         *
  *                 DISPLAY data items, where the source data    *
  *                 is not numeric.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Enterprise COBOL Vx.x sets the sign in  *
  *                      the receiver to x'F', while Enterprise  *
  *                      COBOL V4.2 did not.                     *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  In situations where invalid data is used, the behaviour is
  undefined. Enterprise COBOL Vx.x set the sign to x'F' because
  it is correct that unsigned numeric data items should have a
  sign of x'F'. Enterprise COBOL V4.2 and earlier did not do this.
  

Problem conclusion

• To maintain compatibility with Enterprise COBOL V4.2 and
  earlier for customers using invalid data, Enterprise COBOL Vx.x
  was changed to no longer set the sign of an unsigned numeric
  USAGE DISPLAY receiver to x'F' unless the sign bits in the
  sender were x'F'.
