Prolegomena to the phenomenology of the parametric behaviour of TeX
Abstract
TeX users certainly encoutered situations, where TeX suprised them.
Of course, TeX wizards are never surprised, but not they are addressed
by our presentation. Our aim is to show a few such surprising—at least
at the first glance—cases, without detailed analysis. It is worthy of
knowing that such things may happen in the realm of TeX.
