I found this somewhere, I don't know the source. Helpful to build next, previous links also.

sub BuildNextPrevLinks {
    my ($query,$blankon,$total,$numdisplay,$position) = @_;
    my ($startno,$endno,$prevstring,$nextstring,$firststring,$laststri
+ng);

    my ($lastpagenum,$laststart);
    return unless ($total || $blankon);
    $numdisplay=15 unless $numdisplay;

    # calculations need to be based on total found not our display tot
+al
    if ($total > $numdisplay) {
        $startno = $position+1;
        $endno = $startno + ($numdisplay - 1);
        $endno = $total if ($endno > $total);
    }
   else {
        # when we have less than the number of rows passed in
        $startno = 1;
        $endno = $total;
    }

    if ($position>=$numdisplay) {
        my $newquerystring;
        my $prevstart = $position - $numdisplay;

        my $prevlink = &EditQueryString($query,'position',$prevstart);
        $prevstring="<a href=\"$prevlink\">Previous $numdisplay</a>";

        my $firstlink = &EditQueryString($query,'position',0);
        $firststring="<a href=\"$firstlink\">First $numdisplay</a>";
    }
    else {
        $prevstring="Previous $numdisplay" if ($blankon);
        $firststring="First $numdisplay" if ($blankon);
   }

    if ($endno<$total){
        my $nextstart = $position + $numdisplay;
        my $how_many_left = $total - $nextstart;

        if ($how_many_left > $numdisplay) {
           $how_many_left = $numdisplay;
        }
        my $nextlink = &EditQueryString($query,'position',$nextstart);
        $nextstring="<a href=\"$nextlink\">Next $how_many_left";

        $lastpagenum = ($total % $numdisplay);
        $laststart = $total - $lastpagenum;

        my $lastlink = &EditQueryString($query,'position',$laststart);
       $laststring="<a href=\"$lastlink\">Last $lastpagenum</a>";
#        $laststring="<a href=\"$lastlink\">Last $lastpagenum</a>";
    }
    else {
        $nextstring="Next $numdisplay" if ($blankon);
        $laststring="Last $numdisplay" if ($blankon);
    }

    return ($firststring,$prevstring,$nextstring,$laststring,$startno,
+$endno);
}
