Diagnostics and printing

[halxd2]

I'v been writting scripts that give the user a count-down until an event is about to start. It worked great:

while($time > 0)
{
   print " " . ' ' x (3 - length($time)) . "$time $text";
   foreach (1..$backcount){print "\b"}
   $time -= 1;
   sleep 1;
}

As I began to put the script up to public use, I removed use diagnositics; Then my code no longer printed. I have it nailed down to
diagnostics. Any one seen this before?

If you are not seeing output as you expect try a $| = 1; in the upper part of your script to turn off buffering. with buffering on sometimes you don't get output to the screen until a /n is printed or the buffer fills.

Thank you. This really should have been a RTFM. But I really
am greatful for the pointer. I never looked into file
printing until you pointed the way
