 MY-BASIC is a lightweight cross-platform easy extendable BASIC interpreter written in pure C with less than twenty thousand lines of source code. MY-BASIC is a dynamic typed programming language. It supports structured grammar, and implements a style of OOP called [prototype-based programming](https://en.wikipedia.org/wiki/Prototype-based_programming) paradigm, furthermore it offers a functional programming ability with [lambda abstraction](https://en.wikipedia.org/wiki/Anonymous_function). It is aimed to be either an embeddable scripting language or a standalone interpreter. The core is very lightweight; all in a C source file and an associated header file; simpleness of source file layout and tightness dependency make it extraordinarily tough. Anyone even C programming newbies could learn how to use it and add new scripting interfaces in five minutes. It's able to easily combine MY-BASIC with an existing project in C, C++, Java, Objective-C, Swift, C# and many other languages. Script driven can make your projects more powerful, elegant and neat. It's also able to learn how to build an interpreter from scratch with MY-BASIC, or build your own interpreter easily based on it.
