The solution is to learn Perl, and to understand what you are doing. Seriously, you can't just make up some syntax and hope that perl will magically convert it into a running, correct program.

Check perlsyn or perlintro for the syntax of the foreach loop.

Writing to FINAL (which you've not opened) is going to be disappointing at run time. use warnings; will catch that (see perllexwarn), and please enable use strict; too. See for example RFC: Tutorial: use strict; now what!? for instructions.
