For this reason, N1237 should contain a restriction (probably in 3.4.1.5) that a BIND(C) procedure is not allowed as a specific procedure within a generic interface: resolving a procedure reference to such a generic procedure would be ambiguous. I'll bring the detailed specs to the meeting. Thanks, Michael PS: Of course, a workaround for users who want to do this is to write a Fortran wrapper, and use that as the specific procedure... ====================================================================== Michael Hennecke http://www.uni-karlsruhe.de/~Michael.Hennecke/ ---------------------------------------------------------------------- University of Karlsruhe RFC822: hennecke@rz.uni-karlsruhe.de Computing Center (G20.21 R210) No longer on BITNET :-( Zirkel 2 * P.O.
