Mar 2015
--------

[Fixed]
- non-identifiers (e.g. numbers) could be bound to forms

- CR/LF and line counting was not handled correctly
- internal: copy_object() was not copying conses correctly
- (append ...) was not working correctly

[Changed]
- LISP_EVAL::execute() method renamed to call_by_name()
- runtime macro _CALL renamed to _CALL_BY_NAME
- internal: moved all code from LISP_MODULE to LISP_CTX
- internal: re-organized runtime library modules
- internal: LISP_LEXER can push/pop current state

[Added]
- added (load "filename" ) function
- runtime macro call_lisp_function()


Dec 23, 2008
------------

- (length) was returning incorrect result
- ICE when printing dotted pair cons'es
- lexer was not allowing floats having no leading zero (e.g. .123)
- rel-ops (= < > <= >= /=) were returning incorrect results for more than 2 arguments
- error if trying to redefine a built-in function

[Changed]
- _LENGTH runtime macro returns integer instead of LISP_OBJECT
- runlisp.bas example with no command line arguments immediately goes to interactive LISP shell
- runtime macro _OBJ(p) now allows pointer arrays - _OBJ(p)(0 to n)

- added (consp <expr>)
- added (integerp <expr>)
- added (numberp <expr>)
- added (zerop <expr>)
- added (listp <expr>)
- added (stringp <expr>)
- LispModule.SetPrintCallBack() and LispModule.GetPrintCallBack()
- LispModule.PrintOut(string) for printing (uses the call back)
- runtime macro _COPY to copy a LISP_OBJECT
- runtime macro _PRINT
- runtime macro _IS_IDENTIFIER
