Apologies, I meant it was undefined if the loop exits normally,
but retains its current value if terminated prematurely. Ah well!
Admittedly I do like concrete rules, and any situations where something
is undefined is explicitly stated. Hopefully we can put this one to bed
now! Back to more exciting research and ventures.

Don't worry, I like investigating this stuff. I don't like the
rule-lawyering
that usually follows ;-)

good enough documentation for me.
It is *not* undefined when the loop is left with break or exit, that's the
point. The ISO is not a very good reference for modern-ish Pascal.
