in reply to 5 of 10?

The principal solution is to export the number of the last entry through post, i.e.: a href="myscript.cgi?entry=5"
Then you can use the following routine in your script:
if ($entry >=5) {my $backnum= $entry-5} else {my $backnum=0}; my $nextnum=$entry+5; while ($entry % 5) { #do your output stuff ; $entry++; if ($backnum) { print "<a href=\"myscript.cgi?$backnum\">Previous</ +a>"}; }; print "<a href=\"myscript.cgi?$nextnum\">Next</a>"}; #other stuff...
However, if you would not use CGI module at all, you may parse parameters as $ARGV[0]
You might make a check for the nnumber of entries not to make your Next link to the enmpy page.

    Not to be a noodge, but isn't that get that pases data through the URL, not post?

    Either way, I'm all about using argv[0] for this sort of thing-- it works great for situations where you need to pass data but don't really need the functionality of a form, and I tend to botch it much less frequently than I botch get and post.
