946: The Javascript fragment returned by this function (no E<lt>scriptE<gt> tag)
947: must be written to the HTML page once. It will prove the Javascript
948: function "change(name, content)". Calling the change function with the
949: name of the section
950: you want to update, matching the name passed to C<changable_area>, and
951: the new content you want to put in there, will put the content into
952: that area.
953:
954: B<Note>: Netscape 4 only reserves enough space for the changable area
955: to contain room for the original contents. You need to "make space"
956: for whatever changes you wish to make, and be B<sure> to check your
957: code in Netscape 4. This feature in Netscape 4 is B<not> powerful;
958: it's adequate for updating a one-line status display, but little more.
959: This script will set the space to 100% width, so you only need to
960: worry about height in Netscape 4.
961:
962: Modern browsers are much less limiting, and if you can commit to the
963: user not using Netscape 4, this feature may be used freely with
964: pretty much any HTML.
