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.
