Thanks. The Data::Dumper bits threw me at first, but since I don't have that module, I'll just ignore those lines.

I assume (dangerous, I know), that I can print the key value pairs with:

while (my ($variable_name, $variable_value ) = each %params) {
    print "Variable name = $variable_name/n Variable value = $variable
+_value\n\n";
}

Yes?

UPDATE
my test/understanding code now looks like this:

#!/usr/bin/perl -wT
# tools.cgi

use strict;
use CGI qw(header start_html Vars pre);
use CGI::Carp qw(fatalsToBrowser);

print header();

print "These are the values submitted:\n\n";
my %params = Vars();

my $count = keys %params;
print $count; 

while (my ($variable_name, $variable_value ) = each %params) {
    print "Variable name = $variable_name/n Variable value = $variable
+_value\n\n";
}

I tried
use CGI qw(:standard :cgi-lib); and
use CGI ":standard"; and both of those threw errors and wouldn't execute. But this third option will run, but gives an output of
These are the values submitted: 0
even though I know there are values. I passed and printed them successfully with 
foreach $sri_variable( $cgi->param){
    print "$sri_variable:\n";
    foreach $variable_value( $cgi->param($sri_variable) ){
        print "  $variable_value\n";
    }
}
