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

  Defines the number of dimensions in an array and the number of
  elements in each dimension.  Statement format:

     DIMENSION a([d1:]d2)[,a([d1:]d2)]...

     a        Is the symbolic name of the array.  If the array
              is not defined in a data type statement, the array
              takes an implicit data type.

     [d1:]d2  Is the optional lower (d1) and required upper (d2)
              bounds of the array.
