But that's a bit of a problem if I *don't* want a value higher than 100. > 2,4,8... * >= 100 2 4 8 16 32 64 128 There is no simple formula I can use at the end to get the sequence to stop where I want. So I have to do something like: my @a = 2,4,8... * >= 100; @a.pop # Use @a Cheers, Daniel. -- I'm not overweight, I'm undertall.
