# Simple Lexical Analyser and Parser #

Currently able to tokenise most of the C language and parse very limited

external declarations, functions, and statements.

See 'simpledecl.c' and 'simplectrl.c' for example files that can be parsed.

'simplefunc.c' is an example file that can be compiled, assembled,

transferred to a 6809 machine and run (it relies on I/O via the monitor ROM

routines of my UK109, but can be modified for other hardware).

Use the '-T' command-line option to enable token-level debugging output.

Use the '-S' command-line option to enable syntax trace output.

## Code Generation ##

Code generation for the 6809 and 6309 using the 'asm6809' assembler.

TODO: add a '-PIC' command-line option for position-independent code.

I think the 6809 architecture is suitable for that.
