APAR status
Closed as program error.
Error description
When a called assembler program returns to the COBOL caller, an incorrect code path may be taken when the calling routine checks the Return-Code Special Register. When the COBOL program is compiled with OPT(2), an incorrect length may used in the comparison for Return-Code Special Register.
Local fix
BYPASS/CIRCUMVENTION: Compile the calling program with OPT(0). Called assembler program should also ensure a valid value in reg15 upon return to the calling COBOL program.
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL 6.4 compiling and * * running programs with the OPT(1|2) option in * * effect and the program contains a CALL * * statement and one of the following is true: * * * * 1) the program contains a reference to the * * RETURN-CODE special register after the CALL * * statement; OR * * * * 2) the CALL statement contains a RETURNING * * phrase and the returned value receiver data * * item is a 2-byte binary numeric item (i.e., * * usage COMP/COMP-4/COMP-5/BINARY) and the * * program contains a reference to that * * returned value after the CALL statement * **************************************************************** * PROBLEM DESCRIPTION: Incorrect run time result. * **************************************************************** * RECOMMENDATION: Apply the IBM-provided PTF. * **************************************************************** The COBOL compiler optimizer could, under certain circumstances, mishandle the RETURN-CODE special register or a 2-byte binary numeric returned value leading to an incorrect result.
Problem conclusion
The COBOL compiler was updated to ensure that program optimization does not lead to incorrect handling of the RETURN-CODE special register and 2-byte binary numeric returned values.
