APAR status
Closed as program error.
Error description
Multiple NOT NUMERIC conditions inside a PERFORM UNTIL results in a missing branch back to code after PERFORM UNTIL statement. This causes runtime errors as control flows into code after procedure that is the target of the PERFORM.
Local fix
Use OPT(0).
Problem summary
**************************************************************** * USERS AFFECTED: Users of Enterprise COBOL V5.1 compiling * * programs that contain multiple conditional * * clauses for a 'PERFORM UNTIL' where one or * * more of the clauses is 'IS NUMERIC', using * * compiler options OPT(1) or OPT(2). * * * **************************************************************** * PROBLEM DESCRIPTION: Runtime abend or unexpected behavior. * * * **************************************************************** * RECOMMENDATION: Apply the provided PTF. * * * **************************************************************** An 'IS NUMERIC' clause for a PERFORM UNTIL loop would alter the control flow of the program when an 'IS NUMERIC' clause is converted to an internal switch statement. In some cases this could cause the control flow to lose track of the PERFORM return statement and cause fall through to post loop code, instead of a branch back to the loop header.
Problem conclusion
The compiler was updated to properly keep track of the PERFORM return statement in cases where the conditional statement of a PERFORM changes control flow.
