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

  SEVERITY:  E

  MESSAGE TEXT:  Untyped name, must be explicitly typed

  EXPLANATION:  The displayed name was not defined in any data type
  declaration statement, and an IMPLICIT NONE statement was
  specified.  Check that the name was not accidentally created by an
  undetected syntax error.  Example:

      DO 10 I = 1.10

  The apparent DO statement is really an assignment to the
  accidentally created variable DO10I.
