hi fella monks, i'm really a newbie in perl, and here's another problem. i'm developing a web-based program wherein i could delete and add files via web. now if i delete a file the script should modify another script, it should change the number of files in the current directory. for example: this is the script that should be modified: 

open(FILE, $file) or die $!;
        @lines = <FILE>;
        close FILE;

        for ($i = 0; $i <= $#lines; $i++) {
          if ($lines[$i] =~ /<% INCLUDE exclusives(\d+)\.tmpl %>/) {
            $num = $1;
            $num = $num == 1 ? 3 : 1;
     $lines[$i] =~ s/<% INCLUDE exclusives(\d+)\.tmpl %>/<% INCLUDE ex
+clusives$num\.tmpl %>/;

          } else {

            next;
        }

        open(FILE, ">$file") or die $!;
        print FILE @lines;
        close FILE;

as you can see the line: 

$num = $num == 1 ? 3 : 1;

knows the number of files which in this case 3 files. now if i delete a file it should replace 3 to just 2. the same if i add a file 3 will turn into 4.... how will i be able to replace the value (3) whenever i delete or add a file via web. thanks in advance.
