Hi, thanks for your reply. How would this assignment work if I was assigning my hash values from a DBI sql statement? More complete code is in my above example:

my $row = 0;
while (my $tmp = $st->fetchrow_hashref()){
    for my $key (keys %$tmp){
        $host_info_REF->{$row}->{$key} = $tmp->{$key};
    }
    $row++;
}
