wanted to draw a box that's counting up for certain time.
Thought I could use the counter but it just displays the box not the

can anyone point it out for me?
thank you.
use warnings;
use strict;
sub counter {
my $count;
my $counting = <<EOF;

You want something more like this:
sub counter {
my $count;
my $clear = `clear`;
my $counting = <<'EOF';
%s====================================================

====================================================
EOF
return sub { local $| = 1; printf $counting, $clear, ++$count }
}
my $yeah = counter();
for ( 1 .. 35 ) {
sleep 1;
$yeah->();
}
