This chapter describes the LispWorks extensions to symbols in the
COMMON-LISP package, which is used by default. This chapter notes only those differences between LispWorks and the ANSI Common Lisp standard.
You should refer to this standard for full documentation about standard Common Lisp symbols. An HTML version, the Common Lisp HyperSpec, is available in the LispWorks IDE via the menu command Help > Manuals > ANSI Common Lisp Standard .
