VMS Help FORTRAN, Data, Arrays, Declarators  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  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
