Error description
When two pointer data items are compared to determine whether they are equal, the generated code does not account for the high order bit. Resulting comparison leads to incorrect code path being taken in the application.

Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V6.1 comparing * * two USAGE POINTER data items where the * * unused bit, for DATA(31), or 8 bits, for * * DATA(24) are not equal. * * * **************************************************************** * PROBLEM DESCRIPTION: The comparison will include the unused * * bits and may produce an unexpected * * result. * * * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * * * **************************************************************** The compiler was generating an instruction that compared 32 bits when comparing pointers, regardless of the size of pointer used.
Problem conclusion
The compiler was fixed to only compare 31 bits for DATA(31) and 24 bits for DATA(24) when comparing pointers.
