ISWIM is an abstract computer
programming language (or a family of programming languages) devised by
Peter J. Landin and first described in his article
The Next 700 Programming Languages, published in the
Communications of the ACM in 1966. The
acronym stands for "
If you See What I Mean" (also said to have stood for "I See What You Mean", but ISWYM was mistyped as ISWIM).
