Eight is the number. Brainfuck has eight instructions, and is the only known example of... a language with only eight instructions? ~~ N (t/c) 00:52, 31 October 2005 (UTC)
Okay the number's 40 f-o-r-t-y, that was from GK. From programming language, under the history of, Konrad Zuse was the only person who thought of using a programming language, this was in the 1940s, the language was Plankalkül. I figured this sounds a bit weak, but until I find something better, this will be my answer. - fiveless 10:35, 31 October 2005 (UTC)
concept-oriented language known to date.
Solution:
40 = fourty (which is alphabetic) = XL in roman numerals = a programming language = only known concept-orientated language.
