It looks like you have an ealier version of Perl where unpack has no sub-templates, altthough I thought it had always been like that. Find out what version you are running (with perl -v) and consider upgrading. I am using v5.8.8 and bmost people use v5.8 or above. In the meantime, replace my @fields = unpack '(A7)*', $binary; with my @fields = $binary =~ /.{1,7}/g;
Groups (or sub-templates, if you prefer) were introduced in 5.8. If you don't have them, it's time to upgrade your Perl. In general, you should keep reasonably up-to-date. Not only are there bug and security fixes between releases, but if you don't keep up with the the major versions, you'll find the advice you get on this list and elsewhere increasingly unhelpful as your Perl slips more and more out-of-date. It also means fewer and fewer modules will compile correctly as authors start to rely on newer behaviors. If you don't have pack groups, that means your system hasn't been updated in at least 4 years (5.8.0 was released in 2002). You wouldn't let your OS go for that long without security fixes. 5.6 to 5.8 was a pretty big jump, too! In the meantime, see the perldoc for perlpacktut for some pointers on using the x-multiplication to do some ad-hoc templating.
