'''K''' denotes a family of programming languages designed by [[Arthur Whitney]] and commercialized by Morgan Stanley, Kx Systems, and Shakti. In 1985, while at Morgan Stanley, Whitney created the statically typed A dialect of APL. His colleagues extended A into [[A+]] in 1988. Finally, Whitney presented the first K implementation in 1992, a "reduced instruction set" dialect which only used ASCII [[glyph|glyphs]] and limited arrays to [[list model|(nested) vectors]]. For a long time, K's main role was as implementation languagesfor [[Q]], the query language of kdb+, which is an in-memory, column-based database. K7 (the first "Shakti K") was the first K to have full Unicode support, and it also uses a limited set non-ASCII glyphs in the core language, for example <source lang=apl inline>Ø</source> and <source lang=apl inline>∞</source>, however non-ASCII glyphs were removed in the subsequent K9. | '''K''' denotes a family of programming languages designed by [[Arthur Whitney]] and commercialized by Morgan Stanley, Kx Systems, and Shakti.
