perlquestion hotshot hello guys!<BR><BR> I have a hash of hashes, for example:<CODE> %hash = { abc => { def => 1, }, ghi => { jkl => 1, }, }; </CODE> What happen if I do:<CODE> delete($hash{abc}{def}); </CODE> am I staying with?:<CODE> %hash = { abc => undef, ghi => { jkl => 1, mno => 1, }, }; </CODE> That was the first question.<BR> My second one is, I'm looping over the hash and delete keys as shown above if fulfilled a condition. If the ansewer to the first question is yes, is there a short way to delete also the first level key ('abc' in the example) when deleted all second level keys under it. In the example, when performing the above <I>delete</I>, i would have like to stay with:?:<CODE> %hash = { ghi => { jkl => 1, mno => 1, }, }; </CODE> Thanks <BR> <div class="pmsig"><div class="pmsig-126161"> <BR><BR> <A HREF="/index.pl?node=Hotshot&lastnode_id=1072">Hotshot</A> </div></div>
