Many of the examples in this manual print text when they are
evaluated. In this manual the printed text resulting from an example
is indicated by ‘<samp><span class="samp">-|</span></samp>’. The value that is returned by
evaluating the expression is displayed with ‘<samp></samp>’
(<code>1</code> in the next example) and follows on a separate line.
<pre class="example"> printf ("foo %s\n", "bar")
-| foo bar
1
