[[M2000 Interpreter]] is an open source Interpreter, written by George Karras, in Preveza Greece, for pupils for education. Is not a language for production, but can be very good for implementation of any algorithm. We can use types, or not for calling purposes, so for small problems there is no need for using types, and can be used like BASIC. There are labels, Goto, Gosub, On Goto and On Gosub to use like retro programming, but there are new types like Events (with a list of functions for multicast calls), Lambda functions with closures, Objects named Groups, with hierarchy of Groups inside Groups, and objects as containers, arrays, inventories (as vectors) and stacks. We can use Threads, and Environment support graphics (using GDI and GDI+), databases, multimedia including midi score player.
M2000 Implementation can be found on GitHub [https://github.com/M2000Interpreter/Version9/wiki], written in Visual Basic 6, so it run on Windows OS and using Wine on Linux too. Scope of this implementation was to expand the language, starting from a BASIC flavor with a combination of Forth's Stack, as Stack of Values, with new features like Events, Lambda Functions, Threads and internal GUI manager. Speed was not the target, but at some developing stages a careful code refactoring produce more speedy results. Master task was to run the code, and anyone to observe the code as it runs. So M2000 works with "heavy" interpret, always code as is, and produce objects which hold state as we wish. Major steps in development was:
