LISP Evaluator for FreeBASIC	Copyright (c) 2007-2017 Jeffery R. Marshall.	An embedded LISP interpreter written entirely in FreeBASIC for use	with FreeBASIC applications. 0. INTRODUCTION	My main motivation for writing this is I like the idea of LISP as a	script or macro language that can be embedded in my programs. My	experience with LISP was with AutoLISP. This version of LISP is	also a single namespace variety. It certainly does not follow any	standard. None-the-less it is very LISP-like.	Using this library is probably not a good way to learn LISP. Use a	real LISP compiler or interpreter for that. But if you do know some	LISP programming, this version will be similar enough to be useful. 1. LICENSE	See the 'license.txt' file in the same folder as this readme.txt 2. COMPILING	To compile the library, use the following commands:	cd src	make	To compile the examples, use following:	cd examples	make	To run the test suite, from main directory	example\runlisp tests\tests.lsp 3. INSTALLING	There is no install script. To use, either copy the library and	include files to an appropriate directory, or include the paths	to ./lib and ./inc as search paths.	To use the library as-is, only the following files are needed	./inc/lisp.bi	./inc/lisp_err.bi	./lib/liblisp.a	To use the library as well as extend the built-in functions, all	of the include files from ./src are also needed. 4. INTRINSIC FUNCTIONS	Following is a list of the built-in functions available from the library.	(~ <number>)	(* <number> number...)	(+ <number> number...)	(- <number> number...)	(/ <number> number...)	(/= <atom> atom...)	(< <atom> atom...)	(<= <atom> atom...)	(= <atom> atom...)	(> <atom> atom...)	(>= <atom> atom...)	(1+ <number>)	(1- <number>)	(abs <number>)	(and <expr>...)	(append <expr>...)	(apply function [list])	(atom <expr>)	(car <list>)	(car <cons>)	(cdr <list>)	(cdr <cons>)	(cond (<expr1> expr2)...)	(cons <expr1> expr2)	(consp <expr>)	(defun <sym> (arglist) <expr>...)	(elt <list> <index>)	(eq <expr1> <expr2>)	(eql <expr1> <expr2>)	(equal <expr1> <expr2>)	(equalp <expr1> <expr2>)	(eval <expr>)	(garbage-collect)	(gc)	(if <expr> <then-expr> else-expr...)	(integerp <expr>)	(lambda expr...)	(last <list>)	(length <list>)	(list expr...)	(listp <expr>)	(load <filename>)	(mapcar <function> <list1...listn>)	(not <expr>)	(nth <index> <list>)	(null <expr>)	(numberp <expr>)	(or <expr>...)	(princ <expr>...)	(progn <expr>... )	(quote <expr>)	(set <expr1> <expr2>)	(setf <sym1> <expr1> [<sym2> <expr2>]...)	(setq <sym1> <expr1> [<sym2> <expr2>]...)	(stringp <expr>)	(unless <expr> else-expr...)	(when <expr> then-expr...)	(while <expr> expr...)	(zerop <expr>) 5. EXAMPLE USAGE IN FREEBASIC	#include "lisp.bi"	using LISP	DIM lsp AS LispModule, expr AS STRING	expr = "(lisp expression)"	lsp.eval( expr ) 6. EXAMPLE PROGRAMS	The directory ./examples have a few example example programs. To	compile all of the example programs, use:	cd examples	make	Each example also has its own instructions for comiling and usage	in the .bas source file. 7.

ACKNOWLEDGEMENTS	Sandro Sigala - That a C version of a simple LISP evaluator existed and	was available under an Open Source license saved huge amounts time.	Thanks to Sandro for slisp-1.2. EOF
