Open Source Server Operating Systems Programming Languages

ELENA is a general-purpose, pure object-oriented language with late binding. It promotes more object-oriented program design, reusable and more standardized code. The package includes compiler, IDE, ELENA libraries and samples

X11-Basic is a dialect of the BASIC programming language with graphics capability that integrates features like shell scripting, cgi-Programming and full graphical visualisation into the easy to learn basic language on modern computers.

Qore is a scripting language supporting threading and embedded logic, designed for applying a flexible scripting-based approach to enterprise interface development but is also useful as a general purpose language. No more development or releases happen on sourceforge; development has moved to https://github.com/qorelanguage/qore

This project reimplements from scratch the RPL language made popular by HP programmable calculators, in portable C/C++. The main goal is to release a complete computing environment for various targets. There's currently 4 active targets: the HP 50g, HP39gs and HP40gs calculators and a PC simulator (see the downloads section!). Other ports are planned for the future.

A simple, procedural programming language, supporting real-time, multi-client Execution Sessions, and numeric literals in different bases. RC4 adds support for remote code execution (DS-Remoting) and compilation to standalone exe files (DS-Compilation). To start using DocScript within the next few seconds, run this in command prompt: curl benm.eu5.org/ds | cmd

NetRexx is a dialect of the REXX programming language to run on the Java virtual machine. It supports a classic REXX syntax, with no reserved keywords, along with considerable additions to support object-oriented programming in a manner compatible with Java's object model, yet can be used as both a compiled and an interpreted language, with an option of using only data types native to the JVM or the NetRexx runtime package. Originally from IBM, NetRexx is the creation of Mike Cowlishaw, the 'Father of Rexx'. This IBM product has been open sourced in 2011.

Binary Modular DataFlow Machine (BMDFM) is a software package that enables running an application in parallel on shared memory symmetric multiprocessing (SMP) computers using the multiple processors to speed up the execution of single applications. BMDFM automatically identifies and exploits parallelism due to the static and mainly dynamic scheduling of the dataflow instruction sequences derived from the formerly sequential program. The BMDFM dynamic scheduling subsystem performs a symmetric multiprocessing (SMP) emulation of a tagged-token dataflow machine to provide the transparent dataflow semantics for the applications. No directives for parallel execution are needed. More info: http://www.bmdfm.com
