<p>It depends.</p>
<p>Write('foobar');</p>
<p>Will write to whatever Textfile is contained in Output and</p>
<p>Write(xyz, 'foobar');</p>
<p>Will write to the xyz Textfile. And these Textfiles can basically be anything. By default Output simply writes to StdOut (there's also a variable for StdErr, but I have forgotten how it's called...), but you could also use an implementation that writes to a TStream or one which uses sockets. It's quite flexible...</p>
