![]() The size and range of such a multidimensional array is always given for the highest, leftmost array - the parent array. They may be single or multidimensional - the latter being an array of arrays (of arrays etc). These are defined with fixed, unchangeable sizes. The Array keyword provides single and multi dimensional arrays (indexable sequences) of data.
