The problem you're seeing has to do with the return call; what it does is just that -- returns the value AND stops execution of the subroutine. So, where your sub has:

return $first; return $second; return $third; return $forth; return $others;
The only value returned is $first; the rest of those are ignored. What you apparently want to do is return a list, and fortunately, that's easy to do:
return ($first, $second, $third, $forth, $others);

or, better yet, since your names clearly suggest an *array*, why not return an array and avoid declaring so many variables?

Your code has a number of other issues (e.g. you pass in a scalar, and yet your subroutine is built to deal with an array, you don't use the return value of your subroutine at all), but I'll just stop here and let others help you out with those issues.

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.
