in reply to Re^3: printing during process
in thread 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

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