Rather than ammend that post, it's probably easier just to comment on it...

I'm no longer confused about what the intentions were with $txt = <$fh>. It's clear that it was simply reading from the filehandle (don't you just hate mondays? ;)

Anyhow, my question still stands about the overall handling of the filehandles.... Specifically this:
<code> use Otherpackage;
socket(SOCK, ....); # ... is just a bunch of args
foo(SOCK);

package Otherpackage;
sub foo {
  my $fh = shift;
  #.....
}

• 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).
