Teddy,
$|=1; is supposed to perl to print to standard out right away instead of buffer
information.
You see, by default Perl buffers what it is going to print out until the buffer is
full, then
prints.
For some reason, when I use $|=1; It seems that the first output to STDOUT is
buffered, but once
it prints the initial buffered part, everything after that is printed immediately.
Regards,
David

Subject: Buffer output?
Hi all,
I've seen the following line in more Perl scripts and even in some Perl
books, but it wasn't very well explained.
$|=1; ## Don't buffer output
What does it mean to buffer output?
Which is the difference if the $| is 0 or 1?
Thank you.
