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. + +License +------- + +BAS 2.4 is released as part of NuttX under the standard 3-clause BSD license use +by all components of NuttX.
