@node External representations (basic)
@section External representations (basic)
-An important concept in Scheme (and Lisp) is that of the @dfn{external representation} of an
-object as a sequence of characters. For example, an external representation of the
-integer 28 is the sequence of characters @samp{28}, and an external representation of a list
-consisting of the integers 8 and 13 is the sequence of characters @samp{(8 13)}.
-
-The external representation of an object is not necessarily unique. The integer 28 also has
-representations @samp{#e28.000} and @samp{#x1c}, and the list in the previous paragraph also has the
-representations @samp{( 08 13 )} and @samp{(8 . (13 . ()))} (see section 6.4).
-
-Many objects have standard external representations, but some, such as procedures, do
-not have standard representations (although particular implementations may define
-representations for them).
-
-An external representation can be written in a program to obtain the corresponding
-object (see @code{quote}, section 4.1.2).
-
-External representations can also be used for input and output. The procedure @code{read}
-(section 6.13.2) parses external representations, and the procedure @code{write} (section 6.13.3)
-generates them. Together, they provide an elegant and powerful input/output facility.
-
-Note that the sequence of characters @samp{(+ 2 6)} is @emph{not} an external representation of the
-integer 8, even though it @emph{is} an expression evaluating to the integer 8; rather, it is an
-external representation of a three-element list, the elements of which are the symbol @code{+}
-and the integers 2 and 6. Scheme's syntax has the property that any sequence of
-characters that is an expression is also the external representation of some object. This
-can lead to confusion, since it is not always obvious out of context whether a given
-sequence of characters is intended to denote data or program, but it is also a source of
-power, since it facilitates writing programs such as interpreters and compilers that treat
-programs as data (or vice versa).
-
-The syntax of external representations of various kinds of objects accompanies the
-description of the primitives for manipulating the objects in the appropriate sections of
-chapter 6.
