for example:
$hash{$key} = @value;
I'm trying to store lines of text as the value in the hash. The idea is that I have a large file full of section of text. At the beginning of each section, I have a bunch of numbers. My program runs through the text, sets the numbers as the key, and the following text as the value...up until the next numbers, which are set as the next key, etc... So, when I want to print out the section, I just have to access the hash by the numbers as the key.//

flintstones => [ "fred", "barney" ],
jetsons => [ "george", "jane", "elroy" ],
simpsons => [ "homer", "marge", "bart" ],
};To add another value into the array you'd simply: %HoA{telettubbies} = [ "tinkywinky", "dipsy", "laa-laa", "po" ]; http://www.perldoc.com/perl5.8.0/pod/perldsc.html#HASHES-OF-ARRAYS | | |
