Examples of Merging Pathnames

Although the following examples are possible to execute only in implementations which permit :unspecific in the indicated position andwhich permit four-letter type components, they serve to illustrate the basic concept of pathname merging.

      (pathname-type
        (merge-pathnames (make-pathname :type "LISP")
                         (make-pathname :type "TEXT")))
     =>  "LISP"
     
      (pathname-type
        (merge-pathnames (make-pathname :type nil)
                         (make-pathname :type "LISP")))
     =>  "LISP"
     
      (pathname-type
        (merge-pathnames (make-pathname :type :unspecific)
                         (make-pathname :type "LISP")))
     =>  :UNSPECIFIC
