MULTIPLE_EXIT_POINTS

Severity: info

A POU has more than one RETURN.

Why it matters. Multiple exits make control flow harder to trace and tend to accumulate dead code or duplicate cleanup. Not universally bad, but worth flagging once you have 3+.

Settings. No check-specific config.

Trigger.

FUNCTION Choose : INT
    IF xFastPath THEN
        Choose := 1;
        RETURN;                    (* exit 1 *)
    END_IF;
    Choose := 2;
    RETURN;                        (* exit 2, fires *)
END_FUNCTION

Choose has 2 RETURN statements
Multi-exit POUs are harder to reason about and to trace. Where
practical, refactor so the POU has a single exit point.

Fix. Restructure with a single return point at the end of the POU, using IF / CASE to set the return variable.
