Hi, Basically I want to check a value in one hash and only set a new entry in another hash if its defined in the first i.e. 
if ( $hash1->{'a'}->{'b'}->{'c'} )
{ $hash2->{'bob'} = $hash1->{'a'}->{'b'}->{'c'}; }

But it strikes me that there must be a more efficient(perlish) way than hitting $hash1 twice? Any views would stop me wasting a lot of time pondering... Cheers Mar
