How can I set a bit to 0 ?

bartender1382 has asked for the wisdom of the Perl Monks concerning the following question:

I feel silly asking this, but...

I know how to set bits, and check for them. What I don't know how to do, nor find on Google,is turn off a specific bit whether it is set or not.

my $stats = 0;
$stats = upload | getTicket | downLoading;
printCLine($stats);

Yes, I can reset every bit minus the one I want, but that feels kludgy
