ELAN - Created 1974 by Technical University of Berlin group, as alternative to BASIC in teaching, for systematic programming, and related styles: top-down, bottom-up, recursive, modular, syntax-directed. Descriptions, brief resource list, documents. English, Deutsch.
Heron - Home site. Has brief description, specification, tutorial, related articles, download.
Kx Systems, Inc. - Makes K, advanced vector oriented, functional language, one of the fastest application development environments (according to Bell Laboratories Benchmarking), and allows very fast processing of large datasets.
Lfyre - General purpose, compiled; high performance, expressiveness, flexibility. Many features found in other languages, and extra features: creating new operators, keywords, programming paradigms. News, download. [SourceForge]
Lucid - Functional dataflow language, invented by Bill Wadge, Ed Ashcroft. Variables and expressions denote streams-sequences of data items. Input and output are streams, so a program is a Unix-style filter. Was basis for French real-time/reactive languages Lustre, Signal.
Multiparadigm Programming Group - At Leibniz Laboratory, Grenoble, France; research topics, news, publications, members. In English and Français.
Nial Systems Ltd. - NIAL, Nested Interactive Array Language, mixes aspects of functional array and procedural languages. Rich primitives set makes it easy, fast to code loop-free data-driven algorithms. Also Q'Nial IDE, and Nial Data Engine embeddable interpreter. [Open Source, Artistic Licence]
Piccola: A Small Composition Language - PI based COmposition LAnguage: research language to explore the paradigm: Application = Components + Scripts. From the University of Berne.
ResearchIndex: From Competition to Amalgamation of Different Programming Paradigms - Describes basic elements (data, actions, tunings, voids, mixtures, ...) and principles of programming (stratification, implicit knowledge, limited freedom, ...), directed to amalgamating different programming paradigms (imperative, object-oriented, functional, constraint, ...) in a unified process of generating computer system models.
Scala - General purpose language; multiparadigm (object-oriented, functional, concurrent elements); statically typed, type-safe; focus: Web services. Successor of Funnel. Interoperates with Java VM or .NET, XML aware. [Open source, BSD-like license]
X Language: xlang - The eXtensible Language: easy to use, multi-syntax, portable set of APIs to create CLI and GUI applications for Unix/X11 and Win32; will ease making big applications, has interpreter/compiler/debugger. [Open Source, GPL]
XLR: Extensible Language and Runtime - XL is designed to implement the ideas of Concept Programming. It can apply to many domains and problem spaces, not only a small subset of the problems users must solve.
