It depends.
Write('foobar');
Will write to whatever Textfile is contained in Output and
Write(xyz, 'foobar');
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...
