It's a reasonable question, but you still haven't posted any code, so you may indeed get dinged. In the monestary, code begets code. If your original post had included some kind of code, you probably would have had a lot more input from monks and might have a working solution by now.

On to your question.

The documentation for the get() method in Net::FTP mentions that for get(REMOTE_FILE[,LOCAL_FILE,WHERE]), LOCAL_FILE may be a filename or a filehandle. If you open() a filehandle for writing you can write as many index files as you want and they will be concatenated in the order they were written. WHERE is optional in the method, but you could use it to skip the first unnecessary header bytes of the index file. You can also open() an "in memory" filehandle that is held as a scalar. This is probably what you want. Here is a quick script that grabs the index files for all 4 quarters in 2 years and writes the concatenated indices to a file. I have also included a commented out option to use a scalar as a filehandle. This is what you will probably ultimately want to use.

#!/usr/bin/perl

use strict;
use warnings;

use Net::FTP;

my $host         = "ftp.sec.gov";
my $username     = 'anonymous';
my $password     = 'yourmail@domain.com';
my $indexdir     = '/edgar/full-index';
my @years        = qw/2005 2006/;
my @quarters     = qw/QTR1 QTR2 QTR3 QTR4/;
my $indexbyfirm  = 'company.idx';
my $indexoutfile   = "./complete_index";

##This opens an "in memory" filehandle as a scalar
#open my $indexsave, '>', \ my $pseudo_file
#    or die "Couldn't open memory handle: $!"; 

open my $indexsave, '>', $indexoutfile
    or die "Couldn't open filehandle: $!";

my $ftp= Net::FTP->new("$host",
            Timeout => 30,
            Debug   => 1)
    or die "Couldn't connect: $@\n";

$ftp->login($username, $password)
    or die "Couldn't authenticate.\n";

for my $year (@years) {
    for my $quarter (@quarters) {
        
        $ftp->cwd("$indexdir/$year/$quarter")
            or die "Couldn't change directories : $!\n";
        
        $ftp->get($indexbyfirm, $indexsave)
             or die "Couldn't fetch $indexbyfirm : $!\n";
    }
}

## You can work with the "in memory" file like any scalar
# print "$pseudo_file";

$ftp -> quit();

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
