a pathname object.
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")) => #P"PS:<FRED>CALENDAR" (let ((*default-pathname-defaults* (pathname "<MARY>"))) (merge-pathnames (make-pathname :name "CALENDAR"))) => #P"<MARY>CALENDAR"
