    A slightly modified version of Mark Howell's Zip V2.0

    This interpreter will run all Infocom V1 to V5 games. It includes
    support for timeouts in Border Zone, screen displays in Beyond Zork
    and implements the #record debugging function, etc.

    -r #    set the right margin

    -f #    set the foreground colour
    -b #    set the background colour
    -e #    set the emphasis colour
    -F #    set the foreground colour for reverse mode
    -B #    set the background colour for reverse mode

    -o      monitor object movement
    -O      monitor object locating
    -a      monitor attribute assignment
    -A      monitor attribute testing
    -H      monitor header flag testing
    -t      set the Tandy bit

Graphic font:

    The graphic font for 'Beyond Zork' is built into the interpreter, so
    you don't need the DOS version of 'Beyond Zork' to view the font; any
    other version will do equally fine. Please note that the graphic font
    cannot be displayed in text mode; this is why Zip switches to graphic
    mode when running 'Beyond Zork'. The new program option -d lets you
    choose a different resolution: -d1 selects low resolution, -d2 turns
    on EGA resolution and -d3 activates VGA mode. If you find the graphic
    mode undesirable, you can force the interpreter to text mode by -d0.
