Not that I know of. I always considered it as a given from the PL/I and COBOL days. Not to spark a discussion, but I never use them, because I prefer my variable references to be very short-lived, by localizing them to stack based ones. The few remaining globals I can remember most of the time.
I will have a look.

Thanks, I mostly ask so a new user can read the file.
I see letter
Could be 'none' is local/automatic variable. 'c' might be
'constant'? This was never part of language so wouldn't be in the
book, but I'd have thought I would have documented it somewhere :-(.
I will look at the source to
figure out what they mean.
OK! A summary would be good when you have decoded it .. I
remember a lot of effort went into making that work
Thanks again about the = sign.
:-) I remember that being especially useful on occasion, when
some variable was referred-to dozens of times but only got changed in three
places -- one of which one had forgotten, but of course that case was always
the culprit for some weird behaviour ...
