+
+<p>In Nyquist, 'filep' is implemented as a Lisp function:</p>
+
+<pre class="example">
+(defun <font color="#0000CC">filep</font> (x)
+  (eq (type-of x) 'FPTR))
+</pre>
+
+<h2>Description</h2>
+
+<p>The 'filep' function returns <a href="t.htm">&nbsp;T&nbsp;</a> if
+'expr' is of type FPTR, <a href="nil.htm">NIL</a> otherwise</p>
