When you print "$a\n"; you are using the tied variable that uses @a; And when you print "$a[0]\n"; you are accessing the array directly. I think you just had an unfortunate variable name, otherwise strict would have complained appropriately. :) -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
