OK, so the problem is to find a place in Hugs that is passed frequently enough, but at which the internal data structures are consistent. How about the start of primPass (called to enter the continuation argument of >>= in the IO monad)? Seems like a safe place to do an IO action. (I don't know why the IO furniture is primitive, but since it's there ...) The top-level loop is presumably another safe place. _______________________________________________ FFI mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/ffi
