<h2>Syntax</h2>
<dl>
<dt>(string-right-trim <i>trim-stuff string</i>)</dt>
<dd><i>trim-stuff</i> - a string expression<br>
<i>string</i> - a string expression<br>
returns - a trimed copy of the string</dd>
</dl>
<h2>Description</h2>
<p>The 'string-right-trim' function takes the 'trim-stuff' characters and
removes them from the right end of the 'string'. The 'trim-stuff' characters
are an un-ordered set of characters to be removed, so any character that
occurs in 'trim-stuff' is removed if it appears in right portion of
'string'. A new string is created and returned as the result of this
function.</p>
<h2>Examples</h2>
<pre class="example">
(string-right-trim "." "....foo....") <font color="#008844">; returns "....foo"</font>
(string-right-trim "<>" "<<<<bar>>>>") <font color="#008844">; returns "<<<<bar"</font>
(string-right-trim "(.)" "..(12.34)..") <font color="#008844">; returns "..(12.34"</font>
</pre>
<p><b>Common Lisp:</b> Common LISP also supports a list of characters as
a valid 'trim-stuff' argument. An example:
<pre class="example">
(string-trim '(#\Tab #\Newline) mystring)
</pre>
<p>XLISP does not support non-string parameters. Porting from XLISP will be
no problem, but modifications will be necessary if porting from Common LISP
code which uses a list of characters.</p>
