The '''Bywater BASIC Interpreter''' (a.k.a. ''bwbasic'') is a BASIC interpreter. It supports a large subset of the ANSI Standard for Full BASIC, including all of the ANSI Standard for Minimal BASIC. Bywater BASIC was written in C, and runs on Unix-like and DOS-based systems (including Windows).

Bywater BASIC can be downloaded from [http://sourceforge.net/projects/bwbasic/ its Sourceforge project].
