Kvikkalkul is a
computer programming language ostensibly developed by the [Swedish Navy]
? in the
1950s and used on the SABINA
? computer. It came to fame in
1994 when someone made an [anonymous post]
? to
usenet regarding it. Probably not a real language, but a joke; like Intercal
? in that respect.
