The packing algorithm is forgiving of all forms of JavaScript with one exception. You must correctly terminate all JavaScript statements with semi-colons. This includes function declarations.

Here is an example of correct, semi-colon terminated JavaScript:

// sample code

var $input, $output;

// notice the semi-colon at the END of function declarations

onload = function() {
	$input = document.getElementById("input");
	$output = document.getElementById("output");

function _packScript() {
	$output.value = pack($input.value);

function _clearAll($focus) {
	$output.value = $input.value = "";
	// the "if" statement is NOT terminated with a semi-colon
	if ($focus) {
