No, sorry, the Fortran-2003 ability to call C functions from Fortran in a standard way is necessary for the Fortran API implementation of libcf. Without the convenience of that new portability feature, we would not have the resources to develop and support the Fortran API for libcf. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: SEH-751076 Department: Support LibCF Priority: High Status: Closed
