The only other thing I can think of that you haven't mentioned is just
cycling through the keys 'till you get one that matches, which is probably
not the fastest approach, but if memory is a huge issue, it's probably one
of the most efficient.
foreach(keys %hash){
if($hash{$_} = $myvalue){
print "I've got a flying machine!\n";
}
}

Subject: Fastest method with a hashes...
I have a hash as follows:
PC1 => Nikola Janceski
PC2 => Some Moron
PC3 => Some Other Moron
etc..
I want to be able to get the key (PC#) using the value, what's the fastest
method?
What I can think of:
a. have a reversed hash of the same info.
b. use that funky module which makes hashes go both ways
c. grep through the values and grab that.
d. Your method here.
THANX!
