<p>Comments in Scheme source files are written by starting them with a
|
||
|
|
semicolon character (<code class="code">;</code>). The comment then reaches up to the end
|
||
|
|
of the line. Comments can begin at any column, and the may be inserted
|
||
|
|
on the same line as Scheme code.
|
||
|
|

|
|
<div class="example lisp">
|
||
|
|
<pre class="lisp-preformatted">; Comment
|
||
|
|
;; Comment too
|
||
|
|
(define x 1) ; Comment after expression
|
||
|
|
(let ((y 1))
|
||
|
|
;; Display something.
|
||
|
|
(display y)
|
||
|
|
;;; Comment at left margin.
|
||
|
|
(display (+ y 1)))
|
||
|
|
</pre></div>
|
||
|
|
|
||
|
|
<p>It is common to use a single semicolon for comments following
|
||
|
|
expressions on a line, to use two semicolons for comments which are
|
||
|
|
indented like code, and three semicolons for comments which start at
|
||
|
|
column 0, even if they are inside an indented code block. This
|
||
|
|
convention is used when indenting code in Emacs’ Scheme mode.
