 Why are existing script interpreters so complex? Why is it so difficult to integrate with them? Why not try MY-BASIC today! Scripting should be simple and enjoyable.

 ## Introduction
 
 MY-BASIC is a lightweight cross-platform easy extendable BASIC interpreter written in pure C with about 7000 lines of source code. Its grammar is similar to structured BASIC. It is aimed to be either an embeddable scripting language or a standalone interpreter. The core is pretty light; all in a C source file and an associated header file. You are able to easily combine MY-BASIC with an existing project in C, C++, Objective-C, etc. Scripting driven can make your projects more powerful, elegant and neat.
