Rodolfo, 25 pt is indeed 25 pt whatever the place, but there are some
notices: if this vertical space lies on a page break, it will be completely
dismissed. Other thing you must take into account is that you may have more
vertical space than that you declared: \parskip and \baselineskip, for
example, usually are rubber lengths (or glues, if you prefer). Another:
plain TeX allows you to set a magnification for your entire document. So, if
you define a magnification 2, you will get 50 pt instead. Ah, "25 pt" is
exactly the same as "25pt plus 0pt minus 0pt". Did I forget something?
