reading array elementsby jeah (Novice)

jeah has asked for the
wisdom of the Perl Monks concerning the following question:
Thanks very much for the feedback, everyone and sorry about any confusion, I hope my questions aren't trivial. I've 4 further questions on Revised Code Below, thanks very much in advance.
1. If I use $in on Lines 6 - 8 and print any elements, the entire lines of the file are returned without being processed (with pipes included). I thought I could substitute $_ with any variable. Why won't it work here?
2. If I use $_ on these lines instead, then I get good results (the specified element on Line 12.
3. If I UnComment Lines 9 - 11, a '1' is returned between the last 2 elements in each line. Why is that?
4. To clarify myself (on moritz's question), even-numbered elements return nothing, eg. if I type print $fields, "\r"; on line 12 in my revised script, I get nothing. I've found that any even number gives me nothing, it's odd, I thought the 0th element would be 'Baw', the 1st element would be 'Vao' and so on. The pipe is discarded by perl, so I don't understand why the even-numbered elements are 'skipped', so to print 'Baw', I type print $fields1, "\r" and to print 'Vao', I type print $fields3, "\r"
My File's data (for testing):
