So I guess it was the following unstated option: You misunderstood the purpose of the check. It isn't checking if the length is zero. It is checking if the pointer is `NULL`, for that would be a problem. Since we'll never pass `NULL`, the check will always be false, and that's a good thing.	[reply] [d/l] [select]
