I seek the wisdom of my fellow monks. Please ponder a web survey that asks the user to rate a list of presentations from 1 to 5:

My Presentation 1() 2() 3() 4() 5()
Next Presentation 1() 2() 3() 4() 5()
There is a total of 23 presentations.

There are three peices of information I am trying to gather into a data structure:

  1. The variable name for each presentation passed to the cgi (name=s1. from s1 to s23).
  2. The proper name of each presentation.
  3. The grade of each presentations. This is the value of the variables in 1.

At first I thought about this: 

my %presentations = (
  s1 => "My Presentation',
  s2 => "Next Presentation',
...
  s23 => 'Last Presentation',
);

# Get param answers for presentations
foreach $key (keys %presentations){
  $pres_answ { $presentations{$key} } = param($key);
}

At that point I realized that I would have a problem with order. I want to organize the answers in the same order that they appear on the form. Hashes do not retain that order. How would you go about organizing this data in order to preserve their order?
