        9/01    Why won't Stata allow large datasets even when I am
                using a 64-bit Irix machine?

        op. sys. refuses to provide memory;
        You attempted to set memory or set matsize and, although
        the request seems reasonable to Stata, the operating system
        has refused to provide the extra memory.
