Current Directory

• (current-directory [path]) gets or sets a string path that determines the current directory. When the parameter procedure is called to set the current directory, the path argument is expanded and then simplified using simplify-path (see section 11.2.1) and converted to an immutable string; expansion and simplification raise an exception if the path is ill-formed. Otherwise, if the given path cannot be made the current directory (e.g., because the path does not exist), the exn:i/o:filesystem exception is raised.
