Sorry, "Undefined subroutine &main:: called at (eval 14)D:/software/Perl/lib/perl5db.pl:646 line 2, <$lh> line 7." This is the error I see in perl's debugger as I try each variation. If I try just running it without debug, I get "Can't use string ("") as a subroutine while "strict refs" in use at search.pl line 100, <$lh> line 7." That is true if the curlies are around the whole expression inside the parens or not. Without "use strict" I get the Undefined subroutine error.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
