1. To this hot brain, that looks invalid -- pred(FirstValue) should
be undefined. Do you perhaps mean pred(ord(firstvalue))? Or
maybe I misunderstand what's needed, so ignore and read on.
2. I've forgotten the question so I may be at a disadvantage but:
a) If it's to find out the position in a list, won't simply ord(x) do?
b) If it's to find out the count won't ord(high(setname)) do?
Mustn't forget the low() and high() operators, they can be really
handy in this kind of case...
