hi grandfather,

1. normaly not but it can happen so i load these elements from a file and read it into an array
2. yes they do everytime
3. can be 1 can be 500000
4. the minnimum matching is 4 numbers , the maximum i don't know but i never see everything larger then 14 so 20 shoud be the max
6. im loking for a single best match

here is some sample data for the array

finaly my testing code wich is far from greatness ;)

use strict;
use warnings;
use File::Spec;

open(my $fh_in, '<', 'Script\\onkz.txt') or die("open failed: $!");
open(INFILE, '<', 'data.txt') or die("open failed: $!");

my @ONKZ = <$fh_in>;
my $filterregex = join('|',@ONKZ);

while (<INFILE>) {
  if($_ =~ /^($filterregex)/){ 
    print "$&;$'\n"; 
  }

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
