<h2>Syntax</h2>
<dl>
<dt>(prin1 <i>expr</i> [<i>dest</i>])</dt>
<dd><i>expr</i> - an expression<br>
<i>dest</i> - an optional destination, must be a file pointer or
stream, default is <a href="global-standard-output.htm">*standard-output*</a><br>
returns - the expression</dd>
</dl>
<h2>Description</h2>
<p>The 'prin1' function prints the 'expr' to the specified 'destination'.
The 'expr' is printed without a 'newline' character. If 'expr' is a string,
it will be printed with quotes around the string. The 'expr' is returned as
the result. The 'destination' may be a file pointer or a stream. If there is
no 'destination', <a href="global-standard-output.htm">*standard-output*</a> is the
default. The <a href="terpri.htm">terpri</a> function is used to
terminate the print lines produced.</p>
<h2>Examples</h2>
<pre class="example">
(prin1 'a) <font color="#008844">; prints A without #\Newline</font>
(prin1 '(a b)) <font color="#008844">; prints (A B) without #\Newline</font>
(prin1 2.5) <font color="#008844">; prints 2.5 without #\Newline</font>
(prin1 "hi") <font color="#008844">; prints "hi" without #\Newline</font>
(setq f (open "f" :direction :output)) <font color="#008844">; create file</font>
(prin1 "hi" f) <font color="#008844">; returns "hi"</font>
(prin1 1234 f) <font color="#008844">; returns 1234</font>
(prin1 "he" f) <font color="#008844">; returns "he"</font>
(close f) <font color="#008844">; file contains "hi"1234"he"</font>
</pre>
<p><b>Common Lisp:</b> Common Lisp specifies that 'pprint' with a
'destination' of <a href="nil.htm">NIL</a> will go to
<a href="global-standard-output.htm">*standard-output*</a>. XLISP does not send the
output to <a href="global-standard-output.htm">*standard-output*</a> with a
'destination' of <a href="nil.htm">NIL</a>. Common Lisp also
specifies that a 'destination' of
<a href="t.htm"> T </a> will be sent to
*terminal-io*, which is not defined in XLISP by default. XLISP does not
allow <a href="t.htm"> T </a> as a valid argument
for 'destination'.</p>
<p>See the
<a href="../manual/xlisp-man-027.htm#prin1">prin1</a>
function in the <nobr>XLISP 2.0</nobr> manual.</p>
