VMS Help FORTRAN, Error Messages, Compilation Errors, UNSUPPTYPE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  SEVERITY:  I

  MESSAGE TEXT:  CDD description specifies an unsupported data type

  EXPLANATION:  The Common Data Dictionary description for a
  structure item attempted to use a data type that is not supported
  by Compaq Fortran.

  The Compaq Fortran compiler makes the data type accessible by
  declaring it as an inner structure containing a single unnamed
  field (%FILL field) that is a LOGICAL*1 array with an appropriate
  dimension.  Change the data type to one that is supported by Compaq
  Fortran or use the Compaq Fortran built-in functions to manipulate the
  contents of the field.
