a)The html source also contains a line
<script type="text/javascript" src="jspost.js"></script>
That is a javascript file. It will be loaded and becomes part of all the
javascript on the page. In that file function createForms() will have been
declared. (Try viewing the js file.)

b)The only difference between "script" and "scr"+"ipt" that I can think of
is to make it harder to find script elements in a file via text search in
the source.
