It is pretty compatible to typical BASIC interpreters of the 1980s, + unlike some other UNIX BASIC interpreters, that implement a different + syntax, breaking compatibility to existing programs. Bas offers many ANSI + BASIC statements for structured programming, such as procedures, local + variables and various loop types. Further there are matrix operations, + automatic LIST indentation and many statements and functions found in + specific classic dialects. Line numbers are not required. + + The interpreter tokenises the source and resolves references to variables + and jump targets before running the program. This compilation pass + increases efficiency and catches syntax errors, type errors and references + to variables that are never initialised. Bas is written in ANSI C for + UNIX systems. + + Please do "make check" after compiling bas to run a couple regression + tests. + +License +======= + BAS 2.4 is released as part of NuttX under the standard 3-clause BSD license + use by all components of NuttX.
