Assuming you have started it with the initial memory image,
lispinit.mem then to quit go:

(bye)
or
(quit)
or
(exit)
or just <Control-Z> enough times should also do it.

The file opening/closing stuff can be done in a variety of ways and
you should really have a LISP book, e.g. Common Lispcraft by
R. Wilensky or the official LISP book called Common Lisp, the Language
by Guy L. Steele (but that costs an arm and a leg so I reccommend some
other way of learning!).

Here's a simple one that should get you going:

(with-open-file (infile "test" :direction :output)
 (princ "Hello, this is a test" infile)
 (terpri infile)
 (princ "Bye now" infile)
 (terpri infile)
)

The analogue for reading from a file can hopefully be guessed from
this one.  Note that the file is both opened and closed byu this
example which is tidy.

Hope that helps,
