**●值类型:**

an *object*.

**●初始值:**

**●详情:**

The *variables* *****, ******, and ******* are maintained by the *Lisp read-eval-print loop* to save the values of results that are printed each time through the loop.

The *value* of ***** is the most recent *primary value* that was printed, the *value* of ****** is the previous value of *****, and the *value* of ******* is the previous value of ******.

If several values are produced, ***** contains the first value only; ***** contains **nil** if zero values are produced.

The *values* of *****, ******, and ******* are updated immediately prior to printing the *return value* of a top-level *form* by the *Lisp read-eval-print loop*. If the *evaluation* of such a *form* is aborted prior to its normal return, the values of *****, ******, and ******* are not updated.

**●例子:**

(values 'a1 'a2) => A1, A2 'b => B (values 'c1 'c2 'c3) => C1, C2, C3 (list * ** ***) => (C1 B A1) (defun cube-root (x) (expt x 1/3)) => CUBE-ROOT (compile *) => CUBE-ROOT (setq a (cube-root 27.0)) => 3.0 (* * 9.0) => 27.0
