That depends on what you mean by "does not work". I'll assume you're not using layers for the moment. If that is the case, then binmode doesn't really have any work to do on Unix. You can just read and write your binary data. This has been the case since Perl 3, about 13 years ago I think. > I was thinking that I would record the output from Data::Dumper into a > scalar and write this scalar in binary mode to the disk.
