Oh yes, you will be an expert on references and complex data structures after this ;-)

One advice: You could store your attributes (i.e. AA, 5 'N' etc.) in strings (concatenated by ':' for example) or in arrays (i.e. index 0 would be 'AA', index 1 the dimension...). But usually the most maintainable way to do this is with a hash.

#add values
$fields{$database}[$fieldno]{dimension}=5;
$fields{$database}[$fieldno]{type}='N';

# check if an attribute 'something' exists
if (exists $fields{$database}[$fieldno]{something}) {
