Expanding on hh, quite to the contrary: The basic idea of LaTeX has been to
/hide/ major features of TeX from users in order not to trouble them too
much. LaTeX2e provides \settodepth, \settoheight, \depth, \height (see
LaTeX Companion Appendix on boxes like \raisebox), but it is not clear to
me whether this was meant to explain the ideas of depth, height, reference
point, vertical positioning of vertical boxes to a LaTeX audience. I think
p. 63 of Knuth's TeXbook is the starting point for understanding these
matters. As long as you don't understand the TeX engine behind LaTeX, you
may be puzzled by LaTeX very often.

Did I help??? Anyway, I must stop here -- Uwe.
