Whatever the case, please don't do something idiotic like declare

Hi Charlie,
I don't do that but I thought using varchar(n) fields were supposed to
be space-efficient in a sense that it just used a extra 1 or 2 bytes up
front at the head of the record to identify the true length? It's not
really allocating the space like a CHAR(n) field would...right?
