is it possible to use an array as the value for a hash?
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.//

i've found a work around for my problem. i just set the the sections so they're all one line. adn thus i dont' need an array, just a regular scalar. and, it solved one of my other problems. however, i'd still like to know if an array can be used in such a situation.//

do you mean the whole array and all it's contents or just one item from it?

the entire array. so can the value will be a list rather than a scalar?//

yeh, you can do this. Just make a hash of arrays smile

From perldoc:
Code
%HoA = {
     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" ];
