Thank you for responding - as a newbie to PHP, HTML, and JavaScript, the cookie approach is a little too complex for me. However, after googling some more, I came across the following approach which seems to be simple and works well:
(a) enclose the result table within a form, specifying the form name as "results", the "post" method, and "action" as the page url to be loaded when the anchor is clicked.
(b) insert a hidden field ("seqnum") within the form.
(c) In the php code which builds the table, for the anchor link, use the following code: ($seqno is the data to be passed)
print "<a href=\"javascript://\" onclick=\"document.results.seqnum.value=$seqno;document.results.submit();\">";
Result: $HTTP_POST_VARS['seqnum'] will be set to the sequence number.
The only downside to this method seems to be that the "visited" anchors do not change color. Can anyone suggest how to fix that?

But you /can/ use JS to set a cookie, which can be retrieved (and stored in a session variable if you want) by PHP.
