[Struppi]

Klaus hatte mir einen Link zugeschickt, da sprach man von diesen zweidimensionalen Arrays, ich hatte nur den Sprachgebrauch angewandt.

The most important thing to understand about all data structures in Perl -- including multidimensional arrays--is that even though they might appear otherwise, Perl @ARRAYs and %HASHes are all internally one-dimensional. They can
                                            ^^^^^^^^^^^^^^^^^^^^^^^^^^
hold only scalar values (meaning a string, number, or a reference). They cannot directly contain other arrays or hashes, but instead contain references to other arrays or hashes.
