in reply to How to dynamically update value in STDOUT?

I think you are looking for a carriage return (without line feed):

sub do_stuff { sleep 2; # for the sake of the example .. } $|=1; # turn off buffering, or you may never see what you write ... my @v = (1, 3, 10, 20); while (@v) { printf "\r%2d", shift @v; do_stuff(); }

print "Just another Perl ${\(trickster and hacker)},"
The Sidhekin proves Sidhe did it!

    Thanks. Yes, that was it. I had tried your suggestion earlier, but forgot the '\r'. It's working now.
