What do I need to do in order to use a filehandle that was opened earlier in a program within a subroutine? I've included an example of the code I have that is not doing what I would like. Basically, I never get any output to the file. If I change it so that it doesn't use the subroutine when writing to the filehandle, it works fine. What am I doing wrong?
This is a buffering issue
Thank you in advance for any help you can provide.

EXAMPLE CODE #########################################
Always use strict and use warnings or the -w flag when developing code
$logfile = "/var/log/logfile"; Open(FILE,">>$logfile");
check if open succeeded open (FILE, ">>$logfile") or die "failed to open $logfile for writing, $!\n";
Add this piece of code and check select (FILE); local $| = 1;
perldoc -q flush perldoc -f select #1 argument form of select perldoc -f print
While(1) { &event_log("Logging some data"); sleep 60; };
Sub event_log { print FILE "LOG MESSAGE: $_[0]\n"; }; #########################################
