in reply to sequential file handling

Here's how to do just the 'round robin' part.
my @dirs = qw{ dir1 dir2 dir3 }; my $num_targets = $#dirs + 1; my $counter = 0; foreach (0..10) { my $target = $dirs[$counter % $num_targets]; print "$_ => $target\n"; $counter++; }
The % operator gives you the remainder of the division of $counter / $num_targets, which will be 0, 1 or 2 for any value of $counter. Use that number to select the proper directory out of the array.

Run this little snippet and you can see the result...

[Corion]: (one of my scripts simply catches high amounts and I phone people making that trade, ideally before the payment is due)
[Corion]: The sad thing is that my script sits at the end of the pipeline and can only look at the payments due today or tomorrow basically, while there are many more systems further up in the pipeline
[GotToBTru]: better late than never, I guess
[Corion]: GotToBTru: Sure - there is a long and sad story of many frantic cleanups that led us to implement this notification ;)
