<h2>Syntax</h2>
<dl>
<dt>(dribble [<i>file-str</i>])</dt>
<dd><i>file-str</i> - a string expression for a file name<br>
returns - <a href="t.htm"> T </a> if the transcript
is opened, <a href="nil.htm">NIL</a> if it is closed</dd>
</dl>
<h2>Description</h2>
<p>The 'dribble' function, when called with a 'file-str' argument, opens the
specified file and records a transcript of the XLISP session. When 'dribble'
is called with no 'file-str' argument, it closes the current transcript file
[if any]. 'dribble' will return
<a href="t.htm"> T </a> if the specified 'file-str'
was successfully opened. It will return a
<a href="nil.htm">NIL</a> if the 'file-str' was not opened
successfully or if 'dribble' was evaluated to close a transcript.</p>
<h2>Examples</h2>
<pre class="example">
(dribble "my-trans-file") <font color="#008844">; open file "my-trans-file"</font>
<font color="#008844">; for a session transcript</font>
(+ 2 2)
(dribble) <font color="#008844">; close the transcript</font>
</pre>
<p><b>Note:</b> It is also possible to start a transcript when invoking
XLISP. To start XLISP with a transcript file of 'myfile' type in
<nobr>'xlisp -tmyfile'.</nobr> <nobr>[I haven't</nobr> tested this with
Nyquist.]</p>
<p>See the
<a href="../manual/xlisp-man-031.htm#dribble">dribble</a>
function in the <nobr>XLISP 2.0</nobr> manual.</p>
