TS 29113 says nothing new about type LOGICAL arguments. They are covered in the base F2008 standard. Cheers, Bill On 2/26/13 4:05 PM, Rolf Rabenseifner wrote:

Is TS 29113 changing something in this case? I.e., does TS 29113 allow LOGICAL dummy arguments in BIND(C) subroutines?

In particular, the C function is not using _Bool. It would seem to be more consistent for the Fortran interface to specify the argument as

INTEGER :: FLAG

or, better

INTEGER(c_int) :: FLAG.

FWIW, the MPI Fortran interfaces have always used LOGICAL for boolean values, not INTEGER. It would be weird to change them now.
