I don't think that RPG programmers deal with capabilities, so, the stock microprocessor needs only a stock RPG. What other languages are of importance on the AS/400? What is the OS written in, and are capabilities actually explicit at the source level? My experience with software-based capabilites has been positive, so it's not clear to me, offhand, that a stock RS/6000 is out of the question. -- Don D.C.Lindsay Carnegie Mellon Computer Science
