NUMBER:  65

  ERROR CODE:  E

  MESSAGE TEXT:  Floating invalid

  EXPLANATION:  During an arithmetic operation, the floating-point
  values used in a calculation were invalid for the type of operation
  requested, or invalid exceptional values.  For example, this occurs
  when requesting a log of the floating-point values 0.0 or a
  negative number.

  For certain arithmetic expressions, specifying the /CHECK=NOPOWER
  qualifier can suppress this message.  For information on allowing
  exceptional IEEE values, see the HP Fortran for OpenVMS User Manual.
