Here's something to help you get started. Notice in the first pass, I grabbed the 3rd record. And in the second pass, I printed the 2nd record.
#!/usr/bin/perl
use strict;
my $data_pos = tell DATA;
my $record;
while (my $line = <DATA>) {
chomp( $line );
$record = $line if ( $line =~ /^:16R:USECU/ );
}
seek DATA, $data_pos, 0;
while (my $line = <DATA>) {
chomp( $line );
print "$line\n" if ( $record && $line =~/^:16S:GENL/ );
}
__DATA__
:16S:LINK
:16S:GENL
:16R:USECU

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.
