<h3 class="section">5.3 Creating Strings</h3>
<p>The easiest way to create a string is, as illustrated in the introduction,
to enclose a text in double-quotes or single-quotes. It is however
possible to create a string without actually writing a text. The
function <code>blanks</code> creates a string of a given length consisting
only of blank characters (ASCII code 32).
</p>
<a name="XREFblanks"></a><dl>
<dt><a name="index-blanks"></a><em></em> <strong>blanks</strong> <em>(<var>n</var>)</em></dt>
<dd><p>Return a string of <var>n</var> blanks.
</p>
<p>For example:
</p>
<div class="example">
<pre class="example">blanks (10);
whos ans
