Value Type

    a pathname object.

    Initial Value

    An implementation-dependent pathname, typically in the working directory that was current when Common Lisp was started up.


    a pathname, used as the default whenever a function needs a default pathname and one is not supplied.

     ;; This example illustrates a possible usage for a hypothetical Lisp running on a 
     ;; DEC TOPS-20 file system.  Since pathname conventions vary between Lisp 
     ;; implementations and host file system types, it is not possible to provide a 
     ;; general-purpose, conforming example. 
     *default-pathname-defaults*  #P"PS:<FRED>" 
     (merge-pathnames (make-pathname :name "CALENDAR")) 
     (let ((*default-pathname-defaults* (pathname "<MARY>"))) 
       (merge-pathnames (make-pathname :name "CALENDAR")))
