undef is not really a function ... delete is ... undef is (although many might disagree with me) more like a value not unlike 1,2 or 'cowabunga' that just says there is no value (hope this makes sense)
but when u set a hash to undef it effectively deletes the hash from existance ... (again i might be wrong about this one) On Tue, Oct 23, 2001 at 10:39:50AM +0330, nafiseh saberi shaped the electrons to read: > > > hi all... > I read about "undef" a lot > but.. > I dont understand the difference between "undef" and "delete".. ? > and why do we use undef... > thx > __________________________________ > Best regards .........
