Error description
Subtraction changing all instances of BINARY to COMP-5 gives different results between V4 and V6
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V6.2 compiling * * and running programs that contain * * computations that could produce a negative * * result, where the senders and receiver are * * at least 10 digits in length, and the * * receiver is unsigned, and either specified * * as COMP-5 or as BINARY/COMP/COMP-4 with * * compiler option TRUNC(BIN) in effect. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect results at runtime/migration * * problem: A negative result is not * * converted to positive when being * * stored to a 64-bit unsigned binary * * receiver. * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * **************************************************************** The compiler was incorrectly determining that the sign correction to force a positive sign was unnecessary.
Problem conclusion
The compiler was fixed to stop removing the sign correction. This behavior is now compatible with pre-COBOL V5 compilers.
