1. $" = ""; /* set the delimiter to be null */
@buf = (); /* initialise to zero elements */
$buf[0] = "a";
$buf[1] = "b";
print "buffer = @buf\n";
2. Alternatively, printing an array without using double quotes
will result in no separators between array elements
eg. print @myarray => no separators
print "@myarray" => will use separators
