in reply to passing arrays

You aren't passing anything into the sub csv

my @array = ( 1, 2, 3, 4, 5 ); csv( @array ); # pass array into csv sub csv { my @passed_array = @_; # reteive array from @_ foreach (@array) { print "$_\n"; } }
Check out perlsub

Please reduce your question to the smallest example of your problem. This not only saves us from having to dig through irrelevant code to find your real problem, but a good portion of the time you'll answer it yourself.

    I know grep! :) I'm passing the the $in variable to readlog() from csv() and returning the @mails array from it.
    while (my $in = @data) { my @mails = readlog($in);
    But i think nothing is coming back.
      Ahhhh... this is why you should reduce your code to the problem. I did not see that buried in the rest of your code.

      you want a foreach

      foreach my $in (@data) { my @mails = readlog($in);

        You're absolutely right. Now the values are passing back, but i have a new problem to sort out. :)
