AUTOCAD's AUTOLISP interpreter is indeed a derivative of the XLISP
interpreter written by David Betz.  Both the AUTOLISP interpreter
and the XLISP interpreter are written in C.

I assume that all the rest of AUTOCAD is also written in C --
maybe with a few lines of Assamly Language thrown in for added
efficiency.  Therefore, AUTOCAD is not a LISP based application,
although some customized systems use a few lines of LISP in order
to provide "higher level" operations which are not built into
AUTOCAD.
