To clarify, my comment regarding the bullets was in conjunction to another's response. It probably would have been best to read the comment as a response, since it appears, at least on my display, indented to the aforesaid comment.
I appreciate the response. I am aware of the forum guidelines. But since my question was a very limited subset of data, namely an array, I was just needing a prompt in how to compare a scalar item to the previous item on the stack. The fence post error served as a necessary reminder to debug, as mentioned by the previous comments.
So my code was
@line = split /\r/m, $file;
for my $line (@line) {
my $header = ((split(/\t/, $line))[0]);
##stuck here as I was unsure how to compare $header to previously seen
+ header
}
So, thanks for your response too. It showed me another way to resolve the issue. Much appreciated.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
