12      67-80
67-89   56

If anyone can help me it would be very good.


RE: how do take out some lines !!

I have not run this, but it should be pretty close.  Inside the inner most 'while', do what ever you like with the numbers.

open(IPF,"<inputFile") or die "Failed to open inputFile, $!\n";
while (<IPF>) { $buffer .= $_; }
close IPF;

# while matching stuff between >>> and <<<
while ($buffer =~ />>>(.*?)<<</gs)
  # catch matched strings in $chunk
  $chunk = $1;
    while ($chunk =~ /\[\w+ (.*?)\]/gs) { $numbers = $1; }

'hope this helps
