in thread 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; } }

HTH.HAND.


$;=sub{$/};@;=map{my($a,$b)=($_,$;);$;=sub{$a.$b->()}} split//,".rekcah lreP rehtona tsuJ";$\=$ ;->();print$/

    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;

    cheers
