I never thought of tieing the variable... this is how I use IO::Scalar when I wish to redirect output.
It's actually more useful for when you just need to have output to a variable rather than to some file handle:
use IO::Scalar;
my ( $STD1 $STD2 );
$STD1 = new IO::Scalar \$STD2;
select $STD1;
print <<DONE;
blah blah blah
All this is being appended to the $STD2 variable
So some more text here and we are...
DONE
open FILE, ">test.txt";
print FILE $STD2;
close FILE;
Yes, odd example since you could have just used:
open FILE, ">test.txt";
select FILE;
print <<DONE;
all that stuff again. I am
DONE
But you get the point...

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).
