#### 25.2.14 disassemble [Function]

`disassemble` fn ⇒ nil

#### Arguments and Values::

fn—an extended function designator or a lambda expression.

#### Description::

The function disassemble is a debugging aid that composes symbolic instructions or expressions in some implementation-dependent language which represent the code used to produce the function which is or is named by the argument fn. The result is displayed to standard output in an implementation-dependent format.

If fn is a lambda expression or interpreted function, it is compiled first and the result is disassembled.

If the fn designator is a function name, the function that it names is disassembled.

(If that function is an interpreted function, it is first compiled but the result of this implicit compilation is not installed.)

#### Examples::

     (defun f (a) (1+ a)) ⇒  F
     (eq (symbol-function 'f)
         (progn (disassemble 'f)
                (symbol-function 'f))) ⇒  true

#### Affected By::

*standard-output*.

#### Exceptional Situations::

Should signal an error of type type-error if fn is not an extended function designator or a lambda expression.
