In most cases that probably won't have a real effect as the array is either set to empty anyway or all it's elements are initialized by the function. That doesn't change the fact however that the behavior *is* there and can potentially lead to hard to debug problems. The only exception for the warning could possibly be SetLength(Result, 0) as that is the equivalent of "Result := Nil" or "Result := []" as 3.2.0 now supports. Anything else can potentially be a bug lying in wait. Regards, Sven
