    Seed7

    Interpreter and compiler for the Seed7 programming language.

    Interpreter, compiler, libraries, documentation and examples for the Seed7 programming language. Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C/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. Object orientation is used where it brings advantages and not in places where other solutions are more obvious. Seed7 spares no effort to support portable programming. Several driver libraries assure that the access to operating system resources such as files, directories, network, clock, keyboard, console and graphics are done in a portable way. Although Seed7 contains several concepts from other programming languages, it is generally not considered a direct descendant of any other programming language.

    Ficl - small systems scripting with OO
    Ficl is a lightweight, embeddable scripting language designed to be incorporated into other programs, and especially embedded systems that may have memory and OS constraints. Applications include scripting, hardware bring-up, rapid prototyping, and system extensions. Unlike Lua or Python, Ficl acts as a component of your system - you feed it stuff to do, it does the stuff, and comes back to you for more. You can export compiled code to Ficl, execute Ficl code from your compiled code, or interact. Your choice.

    Learning programming language for kids

    This is learning programming language for children Karel-3D. By words from LightBot: "Get kids hooked on coding with minutes!" Created by Karel 3D from the 8-bit microcomputer PMD 85-2 in 1986. His later version of Karel the Robot in 3D, created first in the Slovak Republic. JavaScript variant include only one small HTML file tested and works on all devices with keyboard and full JavaScript support in internet browser, or alternative pre-compiled JAVA V8 .jar file with webEngine and JavaFX and code in string. ZIP Contains examples in TXT file. More pictures and examples is here at Wiki. Wiki include ZIP with scan of original historical manuals in Slovak language from years 1987 - 1990 Today exist some variants (not mine) like: LightBot or Swift Playgrounds on tablets. Karel 3D from Version 8 is different from other Karels, can bulid a Bridges.

In Karel, currently can not be use Load or Save ( use Ctrl+C, Ctrl+V between the editor and Notepad ) Tip for Karel: Type command: FAST before commands for demonstrating maximum performance. First KAREL-3D is created in 1986 after Karel the Robot, in Slovakia ( before Czechoslovakia ) on 8 bit microcomputer PMD 85-2 for school kids to learn algorithm and what is programming, teach know how to solve a logical problem, like Spock and his children from the planet Vulcan ( live long and prosper ). because it's fun Actual WebGL version: https://sourceforge.net/projects/karel-3d-webgl/

    Breeze

    eXtensible Stack Based Language

    Breeze is a general-purpose stack-based programming language. The main feature of the language is that the concepts of stack and dictionary are no longer distinct. In fact, dictionary words are replaced by named stacks. The process of defining a word is replaced by "pushing" onto a named stack, and that of executing a word is replaced by "popping" from a named stack. A named stack is called an application. Data and code can be moved between applications by using operations (i.e. other applications) that make use of a default stack as an intermediate. In principle, the language recognizes only numbers that can be organized into lists, which are the only form of aggregation of data/code.
