Re: hash of arrays or separate hashes?

Since hash values can only contain a scalar value you can't actually hold two values. Instead, what you can do is store an array of two values e.g

my %hash = (
  Alpha => [
    37
    [0,0,4,26,0,7] 
  ],
  Beta  => [
    40,
    [1,38,0,0,0,1],
  ],
  Gamma => [
    3
    [1,1,0,0,0,1],
  ],
);

Monks I need all your help again, sorry I new on this.. `Before I use to countfreq for an element using $Elementsfreq{$Element}++; Now to increment the count, do I have to have another variable?, Could + you please tell me what is wrong with the following?: $countElements++; %Elementsfreq = ($Element => [$countElements, [ 0..$index ] ]); $bigramfrequency{$bigram}[0]++; $bigramfrequency{$bigram}[1][$position]++;` [download] Thanks!!
