ARR is a type of declaration capable of replacing the entire bunch of CAT declarations with a single line in a codebook.

This aims to save time and make data structure descriptions more compact, provided they follow a specific pattern. With a single declaration, you can add multiple DICTIONARY variables to ARR, all sharing the same set of categories and labels.
