Binary File

Hello Everybody,

I'd like to write an object into a file.
Let's say an object of class:

(defclass myclass ()
    ((my-slot :accessor my-slot)))

(setf myobj (make-instance 'myclass))

(setf (my-slot myobj) "some string")

I want to write the object myobj to a file, so that afterwards I can
read the file and retrieve the object and the value of my-slot.

any idea?

thanks,

Miro Casanova
