+<h2>Syntax</h2>

+<dl>
+<dt>(subseq <i>string start</i> [<i>end</i>])</dt>
+<dd><i>string</i> - a string expression<br>
+<i>start</i> - an integer expression<br>
+<i>end</i> - an integer expression<br>
+returns - the substring between <i>start</i> and <i>end</i></dd>
+</dl>
+
+<h2>Description</h2>
+
+<p> The 'subseq' function extracts a substring from 'string' starting with
+the 'start' offset and ending with the 'end' offset. The 'start' offset has
+a origin or 0. The substring is returned.</p>
+
+<h2>Examples</h2>
+
+<pre class="example">
+(subseq "12345678" 0) <font color="#008844">; returns "12345678"</font>
+(subseq "12345678" 2) <font color="#008844">; returns "345678"</font>
+(subseq "12345678" 2 4) <font color="#008844">; returns "34"</font>
+(subseq "1234" 3) <font color="#008844">; returns "4"</font>
+
+(subseq "1234" 4) <font color="#008844">; returns ""</font>
+(subseq "1234" 4 2) <font color="#008844">; returns ""</font>
+(subseq "1234" 5) <font color="#008844">; error: string index out of bounds - 5</font>
+</pre>
+
+<p><b>Common Lisp:</b> The 'subseq' function in Common Lisp is intended to
+return a portion of a sequence, a sub-sequence. This function operates on
+lists and vectors [one-dimensional arrays of data], basically ordered data.
+Strings are just one of the valid types operated on by 'subseq' in Common
+Lisp. The XLISP 'subseq' function only operates on strings.</p>
+
+<p>See the
+<a href="../manual/xlisp-man-025.htm#subseq">subseq</a>
+function in the <nobr>XLISP 2.0</nobr> manual.</p>
