NWORKERS ()

  Class:  Elemental function - Specific

  Returns an INTEGER*4 value that represents the total number of
  processes executing an application.  However, since VSI Fortran
  only does serial processing, NWORKERS always returns 1.

  NWORKERS is provided for compatibility with HP Fortran 77 for
  OpenVMS VAX systems.

  This function cannot be passed as an actual argument.
