=================================
``bastest`` Bas BASIC Interpreter
=================================

This directory contains a small program that will mount a ROMFS file system
containing the BASIC test files extracted from the Bas ``2.4`` release.

- ``CONFIG_EXAMPLES_BASTEST_DEVMINOR`` – The minor device number of the ROMFS
  block driver. For example, the ``N`` in ``/dev/ramN``. Used for registering the
  RAM block driver that will hold the ROMFS file system containing the BASIC
  files to be tested. Default: ``0``.

- ``CONFIG_EXAMPLES_BASTEST_DEVPATH`` – The path to the ROMFS block driver device.
  This must match ``EXAMPLES_BASTEST_DEVMINOR``. Used for registering the RAM
  block driver that will hold the ROMFS file system containing the BASIC files
  to be tested. Default: ``/dev/ram0``.

Background
----------

Bas is an interpreter for the classic dialect of the programming language BASIC.
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.
