OpenMusic (OM) is a full visual programming language based on CommonLisp / CLOS. OM is icon oriented, uses extensively drag and drop, and has built-in visual control structures that interface with Lisp ones, such as loop.
Parallaxis is a structured programming language for data-parallel programming (SIMD systems), developed by Thomas Bräunl in 1989. The language is based on sequential Modula-2, but extended by machine-independent parallel constructs. In Parallaxis an abstraction is achieved by declaring a processor configuration in functional form, specifying number, arrangement, and connections between processors. With these "virtual processors and connections", an application program can be constructed independent of the actual computer hardware.
PEBL is software for creating psychology experiments. PEBL offers a simple programming language tailor-made for creating and conducting simple experiments.
(commercial) High Performance Fortran (HPF) extends Fortran 90 to enable simple portable parallel programming on all types of computing systems
Post Scriptum is a programming language for preparing PostScript documents and programs. The language is procedural, and uses classical control structures (functions, loops, and conditional statements) and commonly known data types (numbers, arrays, strings, and dictionaries). Its syntax is simple, clear, and easy to learn. The compiler translates programs written in Post Scriptum directly to a PostScript file, which can be than executed by a PostScript interpreter (such as Ghostscript), printed, or used as a procset, driver, or library.
Fortress is a programming language designed for high-performance computing (HPC) with high programability. Features include implicit parallelism, transactions, mathematical syntax, static checking (but with type inference), and definition of large parts of the language in its own libraries.
PyRAF is a command language for IRAF based on the Python scripting language that can be used in place of the existing IRAF CL.
Q is an interpreted, dynamically typed functional programming language based on term rewriting which allows you to define functions using symbolic equations.
a high level, architecture independent programming language for quantum computers, with a syntax derived from classical
procedural languages like C or Pascal
Quantity Modeling Language
Quantity Modeling Language is a "thing-based" language designed for building Internet-ready, scientific data models. Each "thing" is a "quantity" which may be associated with either a structure or physical phenomena.
Racket (formerly known as PLT Scheme) is a programming language suitable for implementation tasks ranging from scripting to application development, including GUIs, Web services, etc.
REBOL is a multi-platform messaging language

RPilot is an interpreter for the IEEE-standard programming language PILOT. PILOT is a simple language which was designed for use in computer-aided instruction in the 1960's. RPilot is licensed under the GPL.
Simulation and Analysis with Reflective Agents: a multi-agent gaming simulation platform which provides for easy construction and development of gamings
Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C++, and Java. In Seed7, new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept.
Scripting Interface Languages for Object-Oriented Numerics: gives users the ability to rapidly prototype their scientific codes in a simple yet elegant fashion using the popular scripting languages Python and Perl
Simpla is concept language for use in teaching children and adults with no programming experience or computer knowledge whatsoever. Intent is to have a language which is capable of many basic scripting language tasks without adding excess complexity.
a small string processing language designed for creating stemming algorithms for use in Information Retrieval. It comes with several useful stemmers implemented using it
Stratego is a modular language for the specification of fully automatic program transformation systems based on the paradigm of rewriting strategies. The construction of transformation systems with Stratego is supported by the XT bundle of transformation tools. The Stratego/XT distribution integrates Stratego and XT.
commercial web application and web database access tool
The Blue Programming Language
Blue is a high-level programming language designed to support advanced algorithms and techniques used in computer science, engineering, and other mathematically intense fields. It is easy to expand by writing plugin modules in C. Modules can implement types, algorithms, and even programming paradigms.
The Data Language
an Interactive Data Language-compatible incremental compiler. Like Matlab, it is intended for scientific data processing and visualization
TinyaML is a virtual machine, a compiler, and a compiler- compiler, powered by the abstract parser tinyap. It is endian-safe and allows easy bindings of new C APIs into the virtual machine. The VM executes wordcode with a virtual threading model and features a garbage collector. TinyaML allows the user to compile and run assembly code, or plug new grammars for higher-level languages into the parser and implement the methods to compile their ASTs.
