  ***************************************************************
  Rational Developer for System z - Nested array subscripts
  (ctx.X0000000) may not be reset during PL/I XML2LS conversion.
  
  APAR Error Description
  ***************************************************************
  Rational Developer for System z - RDz - v8.0.3.2
  
  When using nested array subscipts, during PL/I XML2LS conversion
  the child array subscript is not being reset on each occurrence
  of the parent array.
  There are two issues caused by the lack of the subscript reset:
  1.) In top-down, the upperbound of each nested array, which is
  automatically computed during a pretraversal of the XML, may be
  larger than needed
  2.) In bottom-up and meet-in-middle, out-of-range subscript
  references may occur during XML2LS conversion.

  There are two issues caused by the lack of the subscript reset:

  larger than needed
  2.) In bottom-up and meet-in-middle, out-of-range subscript
  references may occur during XML2LS conversion.
  
  This problem occurs when the array structure contains an arrays
  indirectly:
  DCL 1 ELE_1,
      2 ELE_2 (3),
         3 ELE_3,
           4 ELE_4(3);
  

Problem conclusion

• The XML2PLI converter has been corrected to allow to handle
  subscripts correctly.
  
  The problem listed in this APAR has been resolved with
  IBM Rational Developer for System z V8.5.1 Refresh Pack which
  is available from the Recommended Fixes support download page:
