In the distant past, when I was an undergraduate at Wits University in Johannesburg (around 1970), someone discovered APL and they posted a 1-line APL program that printed the multiplication matrix for all numbers from 1 to 10. This lead to a flurry of postings on the (real!) bulletin board, but the show-stopper was a very short program written in IBM Assembler language, using macros. The code was written by a brilliant physicist named Colin Marquard who also single-handedly re-wrote (in assembler!) the so-called time-sharing system that we used for our courses. (IBM selectric typewriters connected by a proprietary network to the 360). Colin later had to flee South Africa (see, for example, https://goo.gl/Hw3WWb https://goo.gl/Hw3WWb) because of his anti-apartheid activities.
