Thank you Shawn, that is just what I needed. Further, I learned that
referencing the array of hashes is done like this:
return $self->[$index]{$key};
which works nicely. Thanks a bunch!

Hi,
I would like to make a perl module with an array of hashes as the data
structure, but I am having trouble with the references. I have
declared the data structure in the constructor as follows:
my $self = ({});
my $self = [];
and blessed it with:
bless ($self, $class_name);
but when I try to access the array of hashes, for example with:
$self->[$index]{'team1'} = $words[0];
# This will work even if you don't put any hashes in the array. If the
hash doesn't exists, Perl will create it.
the program gets a run-time error, and I don't know which error
message it is because the module is used in a CGI program and I don't
know how to get at the error messages. What should i do? Am i doing
it all wrong? Thanks in advance.
