in reply to How can I split a string into fixed-length parts, rather than on delimiters?

Yet another way, using the fact that if you put parens around the split() argument, it's kept in the output instead of discarded: 
@parts = split /(.{4})/, '41084109.udp';

After this runs, print "@parts" will give you 
4108 4109 .udp

Obviously, if the filename isn't exactly 8.4, you'll get the wrong answer, but it's an interesting use of split().

    Sounds like an overly complicated way of doing 
    @parts = '41084109.udp' =~ /(.{4})/g;
