<h2>Syntax</h2>
<dl>
<dt>(continue)</dt>
</dl>
<h2>Description</h2>
<p> The 'continue' function attempts to continue from the
<nobr><a href="../manual/xlisp-man-004.htm">break loop</a>.</nobr>
This is valid only for <a href="cerror.htm">cerror</a>s [continuable
errors]. If 'continue' is evaluated while not in a
<nobr><a href="../manual/xlisp-man-004.htm">break loop</a> ,</nobr> an
error is generated:</p>
<pre class="example">
<font color="#AA0000">error: not in a break loop</font>
</pre>
<p>In Nyquist, the error is:</p>
<pre class="example">
<font color="#AA0000">error: this error can't be continued</font>
</pre>
<p>This error does not cause XLISP to go into a break loop. 'continue' never
actually returns a value.</p>
<h2>Examples</h2>
<pre class="example">
(continue) <font color="#008844">; error: not in a break loop</font>
(break "out") <font color="#008844">; break: out</font>
(continue) <font color="#008844">; to continue from break loop</font>
<font color="#008844">; BREAK returns NIL</font>
</pre>
<p><b>Keystroke equivalent:</b> In the IBM PC and MS-DOS versions of XLISP,
a 'Ctrl-p' key sequence has the same effect as doing a (continue). On a
Macintosh, this can be accomplished by a pull-down menu or a 'Command-p'.
<nobr>[I haven't</nobr> tested this with Nyquist.]</p>
<p>See the
<a href="../manual/xlisp-man-022.htm#continue">continue</a>
function in the <nobr>XLISP 2.0</nobr> manual.</p>
