   This and the next function allow you to create small sections of an
   otherwise static HTML page that you can update on the fly with
   Javascript, even in Netscape 4.
   
   The Javascript fragment returned by this function (no E<lt>scriptE<gt> tag)
   must be written to the HTML page once. It will prove the Javascript
   function "change(name, content)". Calling the change function with the
   name of the section 
   you want to update, matching the name passed to C<changable_area>, and
   the new content you want to put in there, will put the content into
   that area.
   
   B<Note>: Netscape 4 only reserves enough space for the changable area
   to contain room for the original contents. You need to "make space"
   for whatever changes you wish to make, and be B<sure> to check your
   code in Netscape 4. This feature in Netscape 4 is B<not> powerful;
   it's adequate for updating a one-line status display, but little more.
   This script will set the space to 100% width, so you only need to
   worry about height in Netscape 4.
   
   Modern browsers are much less limiting, and if you can commit to the
   user not using Netscape 4, this feature may be used freely with
   pretty much any HTML.
