I am posting this to the group for the benefit of other teachers and students out there in netland. Things like system calls are necessarily implementation-dependent in Ada (how could the standard predict system calls in a system-independent way?). These system dependencies are always (at least in my experience with _many_ Ada compilers) pretty well documented _somewhere_. Generally it's in a thick looseleaf binder, one copy of which is delivered with the compiler. In your particular case, you didn't mention whether Penn State is running the IBM/TeleSoft system or the Alsys one. In either case, somebody there is going to have to track down that binder. Start with the system manager for the machine the compiler's installed on, since the book would've come in with the tape and may have been filed with it. Or maybe there is a technical support group at the datacenter that deals with users. But that book is there somewhere. At my institution these notebooks are kept in the tech support offices in our two computer centers. They are thick, expensive to duplicate, and (usually) unnecessary for typical student projects. But it sounds like you are going beyond the straightforward "out of the book" Ada, so you'll have to find that binder. Or maybe you'll get lucky and a TeleSoft or Alsys guy will read our notes and contact you. Good luck! --------------------------------------------------------------------------- Prof. Michael Feldman Department of Electrical Engineering and Computer Science The George Washington University Washington, DC 20052 202-994-5253 mfeldman@seas.gwu.edu ---------------------------------------------------------------------------
