Further to runrig's reply: The presence of the statement
join("\t",@h),"\n";
suggests baperl is not running with strictures (use strict;) or warnings (use warnings;) enabled, which might offer many suggestions about other problems in the code:
>perl -wMstrict -le
"my @h = qw(a bc def ghij);
join(qq{\t}, @h), qq{\n};
"
Useless use of join or string in void context at -e line 1.
Useless use of a constant (
) in void context at -e line 1.
Update: Removed extraneous statement from example code.

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).
