Every character sequence that begins with a 0, F, N, f, or a n is interpreted as the boolean false value. All values are interpreted as the boolean true value. However, there is no full support for a boolean type. Such values are interpreted as a [string value](00001006033500), e.g. with respect to comparing and sorting.
