Re (tilly) 1: our + redo = ???

On line 33 your uninitialized variable was $new_kids. So I looked for that, and I had to wonder if you really meant to write:

sub interact() {
    print 'Current number of children is: ', "$children", '. i.e. thes
+e:', "\n\n"; 
    system('ps -ef | grep tryMore | grep -v grep');
    print "\n\n";
    print 'Minus one for the parent, of course', "\n\n"; 
    print 'How many children do you want to add? [1]: ';
    my $new_kids = <>;
#   ^^ (Your mistake?)
    chomp $new_kids;
    $new_kids = '0' unless $new_kids;
    unless($new_kids) { $children += 1; } else { $children += $new_kid
+s; }
    return; 
}

In response to the note below. Experience consists of recognizing a mistake the second time we make it. *Learning* is when you can recognize that someone else is making the mistake. When I can answer questions fast, it usually is a good sign that I have spent an hour or more making that very mistake in my own code...

I am SUCH a dumb-ass. thank you =) UPDATE someone asked in the CB why I was using redo to exit a for loop. Just to clarify, it's because this is just a prototype for a larger program and that will not do this. I know it's bad form and figured I should note that here so not to set a bad example =) (as if I already didn't do that with such a dumb-ass mistake...) oh, and thanks for the kind words tilly; though, i must say that it's hard to picture you making this mistake in particular =) `"A man's maturity -- consists in having found again the seriousness one had as a child, at play." --Nietzsche` [download]	[reply] [d/l]

/me fumbles to make a painful "New Kids on the Block" pun out of this thread: Is this an instance of "New Kids on the Enclosing Block"? (hmm... no) Out with it, tilly, we know you're a closet New Kids on the Block fan (ad hominem, inciteful hate-speech... next) Duh, they're called "New Kids on the Block", not "New Kids in the Block"! (might be a keeper) Now that's my New Kids on the Block. (being an Abbot was nice while it lasted) Like I've always said, the New Kids on the Block have no value. (ding!) Ah, screw it...

Were I a fan of new kids on the block, would I have zeroed in on that as the error so fast? Well you said you wanted a painful pun...	[reply]
