Please read How do I post a question effectively?. Please be sure when you post that the code runs, and provide expected output from provided inputs, all wrapped in <code> tags. In this scenario, that dangling use  ; at the top of the file is a syntax error and is a red flag that you didn't test what you posted.

What are you using as learning material? Try Learn Perl in 2 hours 30 minutes or http://learn.perl.org. I note that you do not use strict or warnings. It's understandable that an old script might not have these, but any new code should use them. See Use strict warnings and diagnostics or die.

The easiest solution for your spec would be to insert

print "ETXLinkID,TranscomLinkID,TranscomLen,TranscomLenFrac,EtxLenFrac +,EtxLen\n";
before that last foreach loop. Is there subtlety in the challenge I am missing?

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
