  ****************************************************************
  The customer complained that the messages on lines 29 and 38 do
  not really point out that the problem originated on line 28.
  Note that it is completely legal to define a data-item without a
  data-item name, giving only the data USAGE type. The following
  is legal COBOL:
  000028 01 UTF-8.
  This results in the compiler assuming a data-item name of
  "FILLER" and a data USAGE type of "UTF-8" which will be
  propagated to the sub-items below the 01 group data item.
  The programmer did not understand this though, and
  assumed that they were creating a data-item named "UTF-8".
  So the compiler is actually parsing this statement as if it were
  specified as
  000028 01 FILLER USAGE UTF-8.
  

Problem conclusion

• To help the programmer better understand the actual error, the
  IGYDS1161-E error message has been changed from this
  000028 01 UTF-8.
  000029 05 Loop-flag3 Pic 9(01).
  000029==> IGYDS1161-E The "PICTURE" clause
  for item "LOOP-FLAG3" was not compatible with the specified
  "USAGE". "USAGE DISPLAY" was assumed.
  000030 88 Loop-done3 Value 1.
  To the following, which more clearly indentifies the problem
  created by the data-item definition statement on line 28:
  000028 01 UTF-8.
  000029 05 Loop-flag3 Pic 9(01).
  000029==> IGYDS1161-E The "PICTURE" clause in the data
  definition was not compatible with the specified
  "USAGE UTF-8". "USAGE DISPLAY" was assumed.
  000030 88 Loop-done3 Value 1.
  The statement on line 28 is legal COBOL, but the
  definition conflicts with the USAGE type for
  Loop-flag3 as coded on line 29.
