This file demonstrates the differences amongst the quote characters

my ($first, $second, $command);

$first = 34;
$second = "Hello";
$command = "date";

print "\t\$first = $first\n\t\$second = $second\n";
print '\t\$first = $first\n\t\$second = $second\n';
print "\n";
print "date = ",`$command`,"\n";


This is the output of the program

	$first = 34
	$second = Hello
\t\$first = $first\n\t\$second = $second\n
