SIMPLE TURTLE ================ Create simple LOGO programs with commands to control the Turtle and draw amazing images!! Use for STEM, Coderdojo or similar coding events. Recursive REPEAT statements. INSTANT ON / OFF = Turns on / off immediate execution of commands FD x = Forward x pixels BK x = Backward x pixels RT x = Right by x degrees LT x = Left by x degrees PU = Pen Up (Do not draw) PD = Pen Down (Draw) REPEAT x = Creates a loop to run x times which runs any commands within the loop. Place END or ] when closing loop. END or ] = Closes a REPEAT loop. (can be nested) PEN x = Color of pen (0 - 9) SETBG x = Color of background (0 - 9) CS - Clear screen CT - Center Turtle (Return to Home position) RUN = Runs the current list of commands shown on screen DELETE / DEL = Clears the command list RESET = Clears commands and resets your Turtle SAVE filename = Saves a png of the working graphic to your documents folder QUIT

JBasic is a traditional BASIC language intepreter written in Java for command line or embedded use. It supports conventional original DOS and MSBASIC syntax, plus some modern extensions for supporting threads, JDBC, etc. JBasic can be run directly from a shell.

BASIC interpreter for the 16bit PIC microcontroller 24FJ64GA002. The interpreter runs on the chip only, no compiler/tokenizer is needed. Communication with PC is done by USB-to-serial converter cable.

nuBASIC is an implementation of an interpreter of the BASIC programming language and IDE. It has been designed mainly for educational purposes and it is suitable for simple games, educational or small business programs.

nbasic - bytecode compiler+vm for middle level programming language, like basic. nbs - small and fast C-coded object orientated basic (compiler+vm) for embeded applications. Purpose: scripting support for C/C++ project.

This is the windows version of XST Basic. Basic interpreter with C emitter written mostly in C. This also uses the irrlicht 3d library to make it much more capable than the DOS XST Basic 1. Enjoy,

TBasic is an implementation of a minimalist BASIC (based on the Tiny Basic specification but with a few significant additions) in the C++ language. It was written for fun, as a project to create a functional language interpreter from scratch and to be potentially used as a lightweight scripting language (it can either be used as a classic command line BASIC interpreter or as a class that allows a C++ programs to load and run basic programs, register custom basic commands and interact with basic variables).

Napoleon Brandy is development of David Daniels Brandy basic, an interpreter for BBC Basic (or Basic V), This project can not claim ANSI C compliance as Brandy Basic did, but supports Graphics for the platforms implemented. OS currently supported are Win32 and DOS. Currently a preview release as it is functionally incomplete.

Brandy is an interpreter for BBC Basic (or Basic V) that runs under a variety of operating systems. Basic V is the version of Basic supplied with desktop computers running RISC OS. These were originally made by Acorn Computers.

FAF-Basic Interpreter is a Basic Interpreter project written for Win32 or Linux. The Programmes can be interpreted in both systems.

ScriptBasic is a mature Basic interpreter that can be used for server side CGI scripting, utility programming or to develop GUI desktop applications. A multi-threaded HTTP Basic application server is available as well with session support.

A dynamic and object-oriented programming language for developing extensions of modifiable applications. Features: OOP, flexible syntax, vectorial operations, dynamic linked lists, IDE, HTML generator, includeable DLL an so on.

AIML chung is an full AIML1.0 based standalone chat bot engine trial with dll , tts / espeak speech voices, synonyms substitutions, maths parser and 3D photorealistics openGL avatars written in compiled freebasic.Comes with GUI window and console examples, 3D world mode and a dll version to use with other programming languages like c++ or Liberty Basic , or to easily embed in your applications .Talk with your A.I. computer.

AntScript is a scripting API for DarkBasic that allows you to easily open files that are in a human-readable format. This speeds up development because you do not have to write editors.

Atom is a programmable, register-based virtual machine for Win32 computers. The AtomVM can be programmed using a high-level, neo-assembler language called Atom Assembler.

DaddyBASIC was developed in order to provide a means to provide my young boys with a pathway into embedded programming. As of this writing, DaddyBASIC runs on the STM32F103R device, and also can compile and run on a Linux target.

This is an interpreted programming language that is designed to teach young children the fundamentals of programming, hiding away from students the complex concepts of programming, such as parentheses, quotes, data types, arrays, while allowing them to understand the basic concepts of programming, and, move to a more advanced language. It also serves as an exapmle on how to create an interpreter with QBASIC. The interpreter is written in QBASIC, and is licensed under the GNU GPLv2. About the unixname: The "shortname" of the project was a typo, but it was too late when I actually realised it. Features that still need to be implemented: Boolean expressions (IF) (If I ever find a flexible way to implement them, because you can't parse user input to a boolean command in QBASIC, without using a dynamically changed BAS file, which is going to fail if using it compilled) The source code should be compiled with either QB64, QuickBASIC or freeBASIC (with the -lang qb switch enabled

JPNBF is best described as an extension on Urban Müller's Brainfuck Language which features output, input, addition, multiplication, devision, incremention, decremention, conditional looping and exponentation of cells (blocks of memory).

A Javascript MSX-BASIC translator. Run simple MSX-BASIC code directly in the browser, or even embed MSX-BASIC programs on your website :)
