Perl hash definition problem
I am trying to generate a report based on an input file with the following layout:

COMPANY1--SITE1--PROGRAM1--PRODUCT1--PRICE1
COMPANY1--SITE1--PROGRAM2--PRODUCT1--PRICE1
COMPANY1--SITE1--PROGRAM1--PRODUCT2--PRICE3
COMPANY2--SITE1--PROGRAM1--PRODUCT1--PRICE2
etc....

I am facing some issues on how to define an hash or hash of hashes for this. I* need to generate one html output file per COMPANY/SITE with the following format:

PROGRAM -list of PRODUCTS - list of PRICES

Can someone give me a hint on how to define somethnig that makes this possible?

Thanks,
Joao

Bug
I hope this code helps you.

Code:
#!/usr/bin/perl
use warnings;
use strict;

my %programs;

while (my $line = <DATA>) {
    chomp $line;
    my( $company, $site, $program, $product, $price) = split('--', $line);
    push @{ $programs{$program}{$product} }, $price;
}

for my $program (keys %programs) {
    print "$program\n";
    print "list of products: ", join(", ", keys %{$programs{$program}}), "\n";
    print "list of prices: ",
          join(", ", map { @{$programs{$program}{$_}} } keys %{$programs{$program}}), "\n";
}

__DATA__
COMPANY1--SITE1--PROGRAM1--PRODUCT1--PRICE1
COMPANY1--SITE1--PROGRAM2--PRODUCT1--PRICE1
COMPANY1--SITE1--PROGRAM1--PRODUCT2--PRICE3
COMPANY2--SITE1--PROGRAM1--PRODUCT1--PRICE2

Thank you very much for the solution, it works perfect.
Does anybody know how can I tie this hash %products?
I tried to use:
use Tie::IxHash;
my %products;
tie %products, "Tie::IxHash";

But the output is the same as if I did not have any of the lines above?

Any ideas about what am I missing?
