Not quite. That variable activates autoflush, which isn't
quite the same as unbuffered output, on the currently selected
filehandle, which may not actually be STDOUT (see 'perldoc perlvar').
Also,
Try:
$|++;
to unbuffer STDOUT.
Hope this helps - Tobias

Hi
I have a simple script that uses print in a loop to update the screen
something like this:
for ( ) {
.
.
.
print ".";
}
print "\n";
The problem, while within the loop, the screen does not update. Only once
print "\n" is encountered
will the screen display the whole printout.
Suresh,
Why not use brackets?:
print (($char x $number_of_chars . "\n" ) x $number_of_lines, "\n");
that's one way to do it. I did not set the outer brackets. :-*
Thanks

Timothy,
How about this:
print $char x $number_of_chars . "\n" for 1..$number_of_lines;
that's another way to do it. Thanks for the hint. This looks a little
more smarter than the other solution, but that's only my opinion. I find
it more readable.
Thanks

Hi,
I've got the following problem:
use strict;
use warnings;
my $char = "-";
my $number_of_lines = 3;
my $number_of_chars = 20;
print "This is the output I want: \n";
my $line = $char x $number_of_chars . "\n";
print $line x $number_of_lines, "\n";
# I do not want to use the var $line. So ho
