Visual multiparadigm programming: visual + object-oriented (signal flow + data flow); from Proceedings of 10th IEEE/CS Symposium on Visual Languages, St. Louis, USA, 4-7 October 1994. Downloads: HTML, PS.
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.
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.
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]
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.
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]
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.
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]
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]
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.
