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.
