Array elements
Array elements are the scalar data that make up an array. Each element inherits the type, type
parameters, and INTENT, PARAMETER, TARGET, 
PROTECTED, ASYNCHRONOUS, and VOLATILE
attributes from its parent array. The POINTER and ALLOCATABLE attributes are not inherited.
Syntax
You identify an array element by an array element designator, whose form is:
- array_name
- is the name of an array
- array_struct_comp
- is a structure component whose rightmost comp_name is an array
- subscript
- is a scalar integer expression
A subscript can be a scalar real
expression in IBM® Open XL
Fortran. 
Rules
- The number of subscripts must equal the number of dimensions in the array.
- If array_struct_comp is present, each part of the structure component except the rightmost must have rank zero (that is, must not be an array name or an array section).
- The value of each subscript expression must not be less than the lower bound or greater than the upper bound for the corresponding dimension.
- The subscript value depends on the value of each subscript expression and on the dimensions of the array. It determines which element of the array is identified by the array element designator.
Array element order
The elements of an array are arranged in storage in a sequence known as the array element order, in which the subscripts change most rapidly in the first dimension, and subsequently in the remaining dimensions.
For example, an array declared as
A(2, 3, 2) has the following elements:
Position of Array Element Array Element Order
------------------------- -------------------
A(1,1,1) 1
A(2,1,1) 2
A(1,2,1) 3
A(2,2,1) 4
A(1,3,1) 5
A(2,3,1) 6
A(1,1,2) 7
A(2,1,2) 8
A(1,2,2) 9
A(2,2,2) 10
A(1,3,2) 11
A(2,3,2) 12
