      [[ I appoogize for the full quote, but I felt it was needed here]]

        TC++ does support overlays, and that may work, but it will more
    that likely cause ALOT of disk activity. Another route would be to get
    hold of some expanded/extended memory routines. I have seen shareware
    as well as "consumer" type libraries that will manipulate exp/ext mem.
    If you don't mind playing with DOS functions, the INT21 functions up in
    the 0x60 range do memory functions (if memory serves me correctly, I
    don't have exp/ext mem. so I have never played with them)

        Any one else?
