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) {
