melguin, your concept is fine.

But you have a number of minor things wrong with your script which you were apparently unable to diagnose because you were not looking at the error log. So: first and foremost find out where the error log is on your server and get chummy with it. That's your life line. My response here is based on loading your code and then walking through the errors that popped up in the log one-by-one.

The first few things were:
  - colon after EOF in page_bottom
  - no check for undefined param("page") on first call

Here's a working revision of your code (I had to change a few things for my setup that you will want to change back): 

#!/usr/bin/perl -w

use strict;
use CGI qw(param);

my $head  = "Content-type: text/html\n\n";
   $head .= "<html><head></head>\n";
my $foot = "</html>\n";

if (defined param("page")) {
   if (param("page") eq "top") {
      page_top();
      exit;
   } elsif (param("page") eq "bottom") {
      page_bottom();
      exit;
   }
} else {
   page_main();
}

sub page_main {
print <<MAIN;
$head
<frameset rows="50,*">
   <frame src="test.pl?page=top" name="frametop">
   <frame src="test.pl?page=bottom" name="framebottom">
</frameset>
$foot
MAIN
}

sub page_top {
print <<TOP;
$head
<h1>TOP OF THE PAGE</h1>
$foot
TOP
}

sub page_bottom {
print <<BOTTOM;
$head
<h1>THIS IS THE BOTTOM</h1>
$foot
BOTTOM
