Re: Blinking a row

Hey, I just remembered how I used to blink a row in Applesoft BASIC. I think I can emulate that effect in Perl...

sub blinkrow {
  my ($rowtext) = @_;
  while (1) {
    print$/x60;sleep 1;
    print "$rowtext\n"; sleep 1;
  }
}

$;=sub{$/};@;=map{my($a,$b)=($_,$;);$;=sub{$a.$b->()}}

The `\r` carriage return is useful for incrementing counters but can also do blink - If you have to! A reasonable purpose would be say if the nuclear reactor powering you computer is in danger of a China Syndrome meltdown due to problems with the heavy water supply from your municipal authority.... `do{ print 0==$a++%2 ?"Core Meltdown!\r" : " \r"; sleep 1} + while 1;` [download] cheers tachyon s&&rsenoyhcatreve&&&s&n.+t&"$'$`$\"$\&"&ee&&y&srve&&d&&print	[reply] [d/l] [select]
