I have two files; in file 1 I am reading line by line, in file 2 I am changing the delimiter using local ($/) ="" to read one paragraph at a time.

The following is shortened version of what I am trying to do 

$old_pos = 0
while ($A = <FILE1>)
  ($tmp,$pos)= split /\s+/, $A;
   open(FILE2,"<$file2name") or die "cant open $file2name for reading!
+\n";
    local($/) = "";
    seek FILE2, $old_pos, 0;
    while (<FILE2>){
       @lines = split(/\n/,$_);
      ($posB,$posend) = findpos(@lines);
      next if $posA < $posB;
       last if $posA > $posB + $posend;
       processPara(@lines)
     }
    }
    $old_pos = tell FILE2;
}

Basically, instead of opening FILE 2 from the start for every line in file 1, I want to open from the position I was at last time I opened the file. However, based on the time it is taking I dont think it is working. I print out the line number of the first file every 50 lines - the first 50 fly then after that it slows down a lot. Is there something I am not doing correctly, especially with changing the delimiter?

Kind thanks!
