You can also see it working on my site:

scroll down to headings Blog Feeds and Blog Comments to see the read more link.

But note that I could not just assign a value of 1 to the page variable,
if I did that then all the pagelist items had a readmore link showing.
I had to force a check for the [[#readmore]] anchor string in the page,
and give the result to the page variable.

You can also use a perhaps better function instead of StringCount.
This one will check for the occurence of a string in the page:

# add page variable {$ReadMore},
$FmtPV['$ReadMore'] = 'StringExists($pn,"[[#readmore]]")';
function StringExists($pagename,$find) {
   $page = ReadPage($pagename, READPAGE_CURRENT);
   if(strstr($page['text'], $find)) return 1;

And we can modify it to do a bit more work:

# add page variable {$ReadMore},
$FmtPV['$ReadMore'] = 'RMCheck($pn)';
function RMCheck($pagename) {
   $page = ReadPage($pagename, READPAGE_CURRENT);
   if(strstr($page['text'], "[[#readmore]]")) return '%comment%RM%%';

Then use in the pagelist fmt template for the conditional check:

(:if eq %comment%RM%% {{=$FullName}$ReadMore}:)[[{=$FullName}|read more]](:if:)

and use in your page this shorter anchor-pagevariable pair:


The page variable hides itself because it is generated as a comment!

Unfortunately while generating the anchor itself would work,
the conditional check does not, or I have not found out how.
