Rob, I've been trying to recompile code for the RT, and have not been able to get fd-streams to compile. Specifically, the compiler can't pack the 3rd arg to 16bit-system-set. Nothing I've tried has worked. I'm at a total loss of what to do. Therefore, I think that you should fix it. On a pmax: (load "/usr/wlott/search-lists") (load "work:rt-setup") (load "tools:worldcom") Have fun. -William
