An array declarator specifies the symbolic name that identifies an
 array within a program unit and indicates the properties of the
 array.  It has the form:

    a(d[,d]...)   a is the name of the array
                  d specifies the bounds of the array in the form:

                  [dl:]du    dl is the lower bound
                             du is the upper bound

 A subscript qualifies an array name.  A subscript is a list of
 expressions, called subscript expressions, enclosed in parentheses,
 that determine which element in the array is referred to.  The
 subscript is appended to the array name it qualifies.  A subscript
 has the form:

    (s[,s]...)     s is a subscript expression

 A one-dimensional array is stored with its first element in the
 first storage location and its last element in the last storage
 location of the sequence.  A multidimensional array is stored so
 that the leftmost subscripts vary most rapidly.
