An array element is one of the scalar data items that make up an
  array.  A subscript list (appended to the array or array component)
  determines which element is being referred to.  A reference to an
  array element takes the following form:

    array [(s-list)]

      array   Is the name of an array.

      s-list  Is a list of one or more subscripts. The
              number of subscripts must equal the rank of
              the array.

              Each subscript must be a scalar numeric
              expression with a value that is within the
              bounds of its dimension.

  Each array element inherits the type, kind type parameter, and
  certain attributes (INTENT, PARAMETER, and TARGET) of the parent
  array.  An array element cannot inherit the POINTER attribute.

  If an array element is of type character, it can be followed by a
  substring range in parentheses; for example:

    ARRAY_D(1,2) (1:3)    ! elements are substrings of length 3

  However, by convention, such an object is considered to be a
  substring rather than an array element.

  The following are some valid array element references for an array
  declared as REAL B(10,20):  B(1,3), B(10,10), and B(5,8).
