About the only problems I can see is that the Fortran compiler's memory management might have to be more strongly coupled to its associated C compiler, but I am not even certain that is required. Would there be any need for a capability to explicitly delete the dope vector that is implicitly created by such a facility? I am not particularly enthusiastic with the name suggested in J3/00-168, and I am not enthusiastic about overloading RESHAPE, as C scalars and pointers are described as if they are different types unlike Fortran's arrays and scalars. Perhaps MAP_C_POINTER or MOLD_C_POINTER, or MAP_C_MEMORY? ----- End Included Message -----
