How can I use a variable as a variable name?

Try a hash: 

use warnings;
use strict;
use Data::Dumper;
$Data::Dumper::Sortkeys=1; 

my %var;
for ($a = 1; $a <= 10; $a++) {
    $var{'var_' . $a} = 5 + $a;
}
print Dumper(\%var);

__END__

$VAR1 = {
          'var_1' => 6,
          'var_10' => 15,
          'var_2' => 7,
          'var_3' => 8,
          'var_4' => 9,
          'var_5' => 10,
          'var_6' => 11,
          'var_7' => 12,
          'var_8' => 13,
          'var_9' => 14
        };
