The Bywater BASIC Interpreter (bwBASIC) implements a large superset of the ANSI Standard for Minimal BASIC (X3.60-1978) and a significant subset of the ANSI Standard for Full BASIC (X3.113-1987) in C.
BWBASIC is an original creation of Ted A. Campbell, who stopped working on it in 1993. Since then it has received contributions from other programmers: Jon B. Volkoff, Paul Edwards and Howard S. Wulf.
