+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 EscriptE 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, and
+the new content you want to put in there, will put the content into
+that area.
+
+B: 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 to check your
+code in Netscape 4. This feature in Netscape 4 is B 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
