You should learn to use the Data::Dumper module to do your investigation. It is one of the most important perl modules.

use Data::Dumper;

$var{ 'a', 1, 'b', 2 } = 1;
# ^ this statement builds a simple hash table, %var

print Dumper(\%var);

This shows that the above is really...
$VAR1 = {
          'a1b2' => 1
        };
