Chromatic, thanks for your reply. But you're a bit off on the spec.
I don't necessarily want to print the entire row that contains the returned string. I want to:
1. Create a subset (an array), based upon columnar data in File A; the
+ column(s) as specified on the command line. See my example.
2. For each matched index in the array, read File B horizontally, grab
+bing data only from the column(s) that I specified on the command lin
+e.
3. Creating a new file, File C with new column labels.
I apologize profusely if I'm lacking clarity. But, I'm not sure how else to explain my spec, other than how I explained it in my original post. Thanks again, for replying!

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).
