We've used a brute force method similar to this in a recent project:

1. Pass (in a hidden field) the CurrentPage Number for each display
2. Generate the entire list of "results"
3. Take a slice from the list to just send the correct entries

This is simple to code, and makes it easier to let the user jump straight to a particular page, and to choose how many results to see on each page (the bit of code below doesn't do either of these).

my $CurPage = CGI::param('CurrentPage');
if (defined CGI::param('NextPage')){
  $CurPage++;
} elsif (defined CGI::param('PrevPage')){
  $CurPage--;
}

print qq{
  <input type="hidden" name="CurrentPage" value="$CurPage">
};

for my $Entry (@Entries[$CurPage * 5 .. $CurPage * 5 + 4]){
  # Show each entry however you normally would
}
print '<a href="myscript.cgi?Prev=1">Previous</a>' if $CurPage;
print '<a href="myscript.cgi?Next=1">Next</a>'
  unless $CurPage * 5 + 5 >= @Entries;

Some notes:

• The slice line looks a little goofy (adding 4 when we want 5 per page), I could write it as "+5 - 1" (and when we have a variable number of results, we do) but whatever...
• This is pretty wasteful (we do the entire database lookup for each page, then throw away what we don't want)...

Hope this helps a little...
