I'm afraid that I don't have the time to stop and
explain this code, but it might get you started.
#!/usr/bin/perl -w
use strict;
my @films;
{
local $/ = '* ';
@films = <DATA>;
chomp @films;
}
shift @films;
foreach (@films) {
my ($header, $data) = split /\n/, $_, 2;
if (my ($movie, $show)
= $header =~ /Movie="(\w+)"\s+show=(\d+)/) {
my @nums = grep { $_ >= 20 } $data =~ /(\d\d)/g;
my $tot;
$tot += $_ foreach @nums;
print "$movie\t$show\t$tot\n";
} else {
print "Invalid Record: $_\n";
}
}
__END__
* Movie="ABC" show=4
10 20 30 14 90 30
21 13 11 10 09 23
22 05 22 15 19 20
* Movie="XYZ" show=4
10 20 30 14 90 30
21 13 11 10 09 23
22 05 22 15 19 10

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.
