Re: HASH Array advice

No real problem, but it should make you think about using an array in there instead....

my %dict;
$dict{'label'} = ['label 1', 'label 2'];
print Dumper(\%dict);

Thank you for your response... So I must change it to something like this? `%dict =( label => ('label 1', 'label 2') )` [download] What's the pro's of doing it this way?	[reply] [d/l]

That should be: `%dict =( label => ['label 1', 'label 2'] )` [download] Using `[ .. ]` to create an anonymous array. The advantage is that array access is much faster than hash access. A good approch would be to code up both alternatives and benchmark them. -- <http://dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply] [d/l]

Slap me with a wet micro$oft t-shirt for not using `[ .. ]` Had a brain fart for a second using `( .. )` There's not much difference in the bench mark, but i suppose the size of the array makes a difference... and i predict it will become rather large as my program progresses...

as said above, an array would be faster, but I mentioned this mainly in a "right tool for the job" type way. If you are accessing something based on a numeric index, you might as well be using an array. It's what they were designed for. :) --- my name's not Keith, and I'm not reasonable.	[reply]
