Error description
CBL V6.1 Compiler changes required for Runtime IGZ0060W Message Truncation of high order digit positions; ok at CBL V4.2
Local fix
Problem with IGZXPR2 handling exponents less than -12. To work around the problem, change the COMPUTE statement to avoid the negative exponent. Example: the faulting code: 01 ANSWER PIC 9(1)V9(17) COMP-3. 01 TOT-ACTIV PIC 9(13)V9(2) COMP-3. PROCEDURE DIVISION. *==================* COMPUTE ANSWER = 10 ** -17 * TOT-ACTIV GOBACK. Work-around: Change the COMPUTE statement to avoid the negative exponent: COMPUTE ANSWER = 1 / 10 ** 17 * TOT-ACTIV
Problem summary
**************************************************************** * USERS AFFECTED: Enterprise COBOL V5.1.1 users running * * programs compiled with ARITH(COMPAT) that * * contain arithmetic expressions with the * * exponentiation operator (**), where both * * the base and exponent are numeric literals * * and the exponent is an integer less than * * -1. * * * **************************************************************** * PROBLEM DESCRIPTION: The exponentiation result might be * * incorrect. * * * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * * * **************************************************************** Given the following exponentiation in ARITH(COMPAT) mode, COMPUTE RESULT = BASE ** EXPONENT where - RESULT is a COMP-3(PACKED DECIMAL) data item - BASE is a fixed-point literal - EXPONENT is an integer literal less than -1 The COMPUTE result might be incorrect because an overflow occurred internally in the COBOL runtime.
Problem conclusion
The compiler was updated to generate the correct information required by the the COBOL runtime to perform the correct exponentiation calculation.
