module nf95_def_var_m

  ! The generic procedure name "nf90_def_var" applies to
  ! "nf90_def_var_Scalar" but we cannot apply the generic procedure name
  ! "nf95_def_var" to "nf95_def_var_scalar" because of the additional
  ! optional argument.
  ! "nf95_def_var_scalar" cannot be distinguished from "nf95_def_var_oneDim".
