Re^4: printing during process

Here is an example:

sub scanUrl {
  my $_url = $in{url};
  my $_startingNumber = 0;
  my $_tnum = 0;
  my $_endingNumber = 100000;
  while($_endingNumber > $_startingNumber) {
    if($_tnum == 10) {
      print ".";
      $_tnum = 0;
    }
    sleep(1);
  }
}

That does not have any of my tracking code in it, but it is an example, if you run that, it never prints a period until it finishes. How do I get it to print the things I want it to, before it finishes the subroutines or while statement?

thanks,
Richard

it never prints a period until it finishes That is because you did not pay attention to Re^3: printing during process. Cheers, Sören	[reply]

I forgot to add the $_tnum++; and $_startingNumber++; before the sleep...	[reply]
