So, cr88192, we have now discovered that as well as being unfamiliar
with Forth you are also unfamiliar with PostScript.  I'm guessing that
you are not really familiar with *any* reverse polish programming
langauge.  However, you don't let a mere lack of knowledge get in the
way of having an opinion.
