Good. Then the very short summary should be okay: Due to the 22 routines with LEN=*, BIND(C) on the MPI API level should be fully removed. BIND(C) makes sense only on this internal interface, which should be optional. Best regards and happy easter Rolf ----- Original Message -----

Can I summarize your analysis to: - 2 routines with CHARACTER(LEN=*),INTENT(OUT) arguments These routines works with non-BIND(C) and BIND(C), because the application must provide a string-buffer that is large enough.

Except that LEN=* is not permitted with Bind(C), either. For Bind(C), using CHARACTER(len=1),dimension(*) would be fine, though.
