SYNOPSIS
========

**cbmbasic**

**cbmbasic** *program.bas*

DESCRIPTION
===========

**cbmbasic** is a 100% compatible version of Commodore's version of
Microsoft BASIC 6502 as found on the Commodore 64. You can use it in
interactive mode or pass a BASIC file as a command line parameter.

**cbmbasic** does not emulate 6502 code; all code is completely native. On a 1 GHz CPU you get about 1000x speed compared to a 1 MHz 6502.

There are no command-line options.

USAGE
=====

You can use **cbmbasic** in interactive mode by just running the binary
without parameters, or you can specify an ASCII-encoded BASIC program
on the command line. You can also use **cbmbasic** as a UNIX scripting
language by adding a hashbang line to your BASIC program and making
it executable::

    $ ls -l hello.bas
    -rwxr-xr-x  1 mist  staff  40  7 Apr 21:30 hello.bas
    $ cat hello.bas
    #!/usr/bin/env cbmbasic
    PRINT"HELLO WORLD!"
    $ ./hello.bas
    HELLO WORLD!

**cbmbasic** implements a small plugin system that lets developers add
additional statements, functions etc. Right now, you can turn this on
with **SYS 1** (turn off with **SYS 0**) and use the new statements
LOCATE *y*, *x* (set cursor position), SYSTEM *string* (run shell
command) and the extended WAIT *port*, *mask*, which implements the
Bill Gates easter egg.

AUTHORS
=======

**cbmbasic** was ported by Michael Steil and James Abbatiello. The
original 6502 version was written by Microsoft.
