Date: Thu, 22 Mar 2007 07:41:00 -0000	[thread overview]

NAG f95:
  line 4: Recursive invocation of F which has no RESULT clause
(gfortran and ifort allow this)

> recursive function f(i) result(g)
>   integer :: g, i
>   g = 0
>   if (i > 0) g = g(i-1) + 1
> end function

NAG f95: Inconsistent usage of G
ifort: This name has not been declared as an array or a function
gfortran: Cannot assign to a named constant
