<h1><a name="description">DESCRIPTION</a></h1>
<p>Sets file position in FILEHANDLE to be first line greater than or equal
(stringwise) to <em>$key</em>.  Returns the new file position, or -1 if an error
occurs.</p>
<p>The flags specify dictionary order and case folding:</p>
<p>If <em>$dict</em> is true, search by dictionary order (ignore anything but word
characters and whitespace).  The default is honour all characters.</p>
<p>If <em>$fold</em> is true, ignore case.  The default is to honour case.</p>
<p>If there are only three arguments and the third argument is a hash
reference, the keys of that hash can have values <code>dict</code>, <code>fold</code>, and
<code>comp</code> or <code>xfrm</code> (see below), and their correponding values will be
used as the parameters.</p>
<p>If a comparison subroutine (comp) is defined, it must return less than zero,
zero, or greater than zero, if the first comparand is less than,
equal, or greater than the second comparand.</p>
<p>If a transformation subroutine (xfrm) is defined, its value is used to
transform the lines read from the filehandle before their comparison.</p>
