The || is being parsed wrong; use another delimiter for your s///. Also you have a couple of typos past that. A corrected version could look like: my @files = qw(quotePAGE1 quotePAGE2);
for (@files) {
open IN, $_ or die "failed opening file $_, at";
$\ = "\n\n";
my $num = 0;
my($chunk,$q_num,%s_nums,%auth,@s,%subj);
while($chunk = <IN>) {
++$num;
$chunk =~ s|^/-a(\S+)[^/n]*\n|| or
die "no author? file $_, chunk $num; at";
$a = $1;
while($chunk =~ s{/-s(\S+)[^\n]*\n/-q((?:.|\n)+?(?=/-))}{}) {
$q_num = 0;
$auth{$a}->[$q_num] = $2;
@s = split /,/,$1;
for (@s) { (undef($s_nums{$_}) && $s_nums{$_} == 0) || ($s
+_nums{$_} += 1) }
$subj{$_}->[$s_nums{$_}] = $2 for @s;
}
}
}

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).
