PM83631: Nested array subscripts may not be reset during PL/I XML2LS conversion when parent array has different level arrays

Rational Developer for System z Fix Pack 1 (8.5.1.1) for 8.5.1

APAR status

• Closed as program error.

Error description

• Nested array subscripts may not be reset during PL/I XML2LS
  conversion when parent array has different level arrays. Here is
  an example to illustrate the problem:
  
  This problem occurs when the array structure(NODE1) contains
  arrays(NODE2 and NODE4) on different levels:
  DCL 1 REQUEST,
      2 NODE1 (3),
         3 NODE2(1) CHAR(8),
         3 NODE3,
           4 NODE4(3) CHAR(8);

Problem summary

• Users affected:
  Top-down, Bottom-up, Meet-in-middle PL/I XML2LS conversion
  
  Problem descriptions:
  When using nested array subscipts, during PL/I XML2LS conversion
  the child array subscript is not being reset when parent array
  has different level arrays.
  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.
  
  This problem occurs when the array structure(NODE1) contains
  arrays(NODE2 and NODE4) on different levels:
  DCL 1 REQUEST,
      2 NODE1 (3),
         3 NODE2(1) CHAR(8),
         3 NODE3,
           4 NODE4(3) CHAR(8);
  

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 V8.5.1.1 Fix Pack which
  is available from the Recommended Fixes support download page:
