Subroutine prototypes, like "($)" here, generally cause more harm than
good, alas. Most programmers should avoid using them in most cases.

You're using the "name" of the array in scalar context; this gives the
number of elements. From the way you're using $data, you probably
wanted to use list context to get the actual element:
my($data) = @_;

Perl is a case-sensitive language, so the return operator must not be
capitalized. If you've seen RETURN like that in someone else's code,
that's a subroutine call; presumably one that does some special kind
of return operation other than the standard one.
Hope this helps!
