Re: Getting keys/values from a referenced hash

Ira has already shown you how to access your keys so I thought I'd take a moment to suggest a more concise method of reading in your hash:

my $hash = do 'hash.pl';
print $! || $@ || $hash->{'key'};

See 'perldoc -f do' for more details on the effects of 'do FILE'. Cheers, - danboo

Thanks, I'll give it a try! As I come from Pascal and Fortran77 (yikes) I still have some problems with the more advanced (say: efficient) way of accessing data in Perl. And I will need ages to be able to reply properly and not a thousand times like above... ;) Micha	[reply]
