Thanks for that, Lasse! Lots of good references, many of
which I had half-forgotten [or worse]. Sadly, as is the way with
encyclopaedic entries, I also managed to waste a morning chasing
down all those rabbit holes.
One of the rabbit holes that is particularly relevant to
recent threads here was the paper by Hemker and Winter:
Hemker, P.W, & Winter, D.T. (1979). "A preliminary report on
numerical operators in Algol 68." Stichting Mathematisch
Centrum. Numerieke Wiskunde.
http://www.cs.vu.nl/pub/dick/Algol68/TransputHansVanVliet
detailing a system of type and operator definitions to allow
numerical analysis in a natural way. The actual content will be
of limited interest to non-mathematicians/engineers, but shows
how useful operators can be. It's worth the doubters looking at
least at the first real page of text ["Introduction for the non-
ALGOL 68 user"] to see what the point is. These days, those with
deep pockets can use Maple [based around A68!] or Mathematica
instead, but good symbolic algebra packages weren't around in the
1970s.
BTW, while browsing, I realise that I have been allowing auto-completion of "Marc" to "Marcus" in recent articles instead
of the much more famous and helpful A68G guru, Marcel vd Veer.
Apologies to him! I thought it looked wrong, but couldn't quite
see how.
