Re^3: Hash value interpolation

I don't know why you have two hashes in the first place.

my %colors = (
   "1" => "blue",
   "2" => "green",
);

my $COLOR = 2;  # 1..2

sub geth {
   print "$colors{$COLOR}\n";
}

geth();

Or why you aren't using an array.

my @colors = (
   "blue",
   "green",
);

my $COLOR = 1;  # 0..1

sub geth {
   print "$colors[$COLOR]\n";
}

geth();

Thanks for all the help everyone... responding to ikegami's two points, the reason for the two hashes is because I wanted to simplify the code sample to focus on my problem, but the idea was to select a hash table to use based on a calculation. Also, the hash table makes the data elements much more readable for me. Is there a performance gained by using an array over the hash? Thanks gain!	[reply]

the reason for the two hashes is because I wanted to simplify the code You didn't do that. Your data structure is horribly complex. What's the point of having a hash for every key! (And don't say "1" and "2" could be the same string because then your goal makes no sense at all. There wouldn't be a right "hm" to fetch.) Is there a performance gained by using an array over the hash? Performance? Not really. The problem is that emulating a hash using an array is one more thing that can go wrong compared to just using an array.	[reply]

I see your point. I guess I can just pull the value from standard array just as easily based on the position. I'll give that a try. Thanks for the feedback do appreciate it.	[reply]
