/*	Although all other segments of data in this program are described by
	giving the position of the first in the segment and that of the
	first not in the segment (so the size is the difference of the two),
	a `chunk' is given by first and last. This is done because later on we
	are interested in the actual position of the last token of it, and
	the position of the first token not in the segment gives no
	indication about that.
