In [[nested array theory]], a mixed array is one that mixes [[simple scalar]] [[ | In [[nested array theory]], a mixed array is one that mixes [[simple scalar]] [[character]]s and [[number]]s, or simple scalars with arrays which are not simple scalars. Such an array cannot be formed in [[flat array theory]], which does not allow mixing of the character, number, and [[box]]ed types. | ||
Because it must have more than one [[element]], a mixed array must have [[bound]] greater than one, and [[depth]] at least one (in particular, it cannot be a simple scalar). However, mixed arrays with depth one can be formed by mixing numbers and characters. While such an array is [[Simple array|simple]], it is neither a simple numeric nor a simple character array. In some cases it may be referred to as a [[pointer array]], because it is stored using pointers like a [[nested array]]. | Because it must have more than one [[element]], a mixed array must have [[bound]] greater than one, and [[depth]] at least one (in particular, it cannot be a simple scalar).

A non-simple mixed array must contain some simple scalars and some other arrays. As a consequence, it has depth greater than one, but some of its elements have depth zero. Therefore its [[signed depth]] is negative. | A non-simple mixed array must contain some simple scalars and some other arrays.
