Do you mean something like this?
use warnings;
use strict;


my %Defaults = (TEMP => q(\QC:\DOCUME~1\z002n88f\LOCALS~1\Temp\E),
                LOGONSERVER => q(\\MOLLY2),
                NUMBER_OF_PROCESSORS => 2,
                OS => q(Windows_NT));
                
while (my ($key, $value) = each %Defaults) {

    
    if (exists $ENV{$key} and $ENV{$key} eq $value) {
        print "$key is cool\n"; 
    } 
    else { 
        print "$key is $value\n" 
    }
