1.6 Leaving LISP

If at any point you should wish to terminate your current session with the LISP interpreter, most LISPs have some function that will do so. Sunction a function is often called exit. This is a function of no arguments which terminates the current LISP process. Thus executing

-> (exit)

will return the user to the operating system interface from which the LISP process was originally created.

NOTE: There is no standard Common LISP function for returning to the operating system. On LISP machines, no such function exists as there is no notion of a separate operating system.

exit kills the current LISP process, so if you want to play with LISP some more, you will have to create a new process. This new process will not know about any of the things you did in your previoius session.
