I am having an issue with some code I'm writing. I basically want to do the same process for a list of course names (which are all under topic names). I pulled the course names into a hash and the script works fine. The only problem is that there is no rhyme or reason to the order that these courses print out. Ideally, I want them to be ordered by topic name AND course name, though at this point, even having them ordered by topic name alone would be an achievement. I am very, very new to Perl, and I just read somewhere that hashes have no concept of order. Do arrays? I have just tried doing this in an erray, but am having problems with the foreach statement, I guess. Does anyone know how I can order these using a hash? If not, can anyone tell me how to change this into an array situation?? Here's the beginning of my code, up to the "foreach":
#!/usr/local/bin/perl5.005
use lib '../L2e/lib';
use DBI(0.90);
use strict;
use Database;
use CGI qw(:standard);

Database::->db_info_path("../L2e/lib/db.cfg");
my $dbh = new Database;

print "Content-type: text/html\n\n";

#Grab the evaluation responses from the form

my $tc9Questions = param('tc9Questions');
my $tcQ10 = param('tcQ10');
my $tcQ12 = param('tcQ12');

#Get the list of courses

my $title = "select C.il2e002_course_id_k, C.il2e002_course_title_x, 
T.il2e001_topic_id_k from il2e001_topic T, il2e002_course C 
where T.il2e001_topic_id_k = C.il2e001_topic_id_k order by T.il2e001_topic_desc_x, 
C.il2e002_course_title_x";

my %titles = $dbh->fetch_all_hash($title);

foreach my $key (keys %titles)
{
