Error description
Customer reports that when compiling a COBOL program with LP(64) and the source directive >>DATA 31, a Working-Storage item is placed above the 2 GB bar when a REDEFINES is present. The same item is placed below the bar when the REDEFINES is removed. The customer is using IBM Enterprise COBOL for z/OS V6.5.0 P260320. Testcase located in: CBLSERV.T02211.S2788.TESTCASE Where you can find a simple program and a JCL where the behavior is recreated.

Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.5 compiling and * * running programs with the LP(64) option in * * effect, where the program contains a data * * item under the scope of a 'DATA 31' * * directive and the data item is redefined by * * another data item. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect runtime behaviour, including * * a possible runtime abend, due to the * * data item being located above the 2GB * * bar instead of below it. * **************************************************************** * RECOMMENDATION: Apply the IBM-provided PTF. * **************************************************************** The compiler was not correctly applying the DATA directive to redefined data items.
Problem conclusion
The compiler was updated so that the DATA directive is properly applied to redefined data items.
