            Documentation for BJ (Blackjack)

            This (not another Blackjack program) was written to show the
            usefulness of my graphics libraries. While is defaults to
            VGA, it may be used from EGA through the enhanced VGA modes.

            It defaults to mode 18 (12 hex), but to cause it to use
            another mode (at least EGA) merely enter it as the command
            line option.

                 i.e.
                      BJ 16

                 will cause it to use mode 16 (10 hex) and come up on an
            EGA monitor.

                 Generally, any mode between 640 X 350 and 1024 X 768
            that is supported by your system should be acceptable as a
            display mode. For instance with the Orchid Pro-designer and
            a MultiSync-3D, modes 16/18/41/45/46/48/55 are acceptable.

                 While it basically follows the "standard" Blackjack
            rules, no attempt is made to utilize some of the finer
            points of the game, for instance "splitting" or "doubling".

                 The "sound" routines were optimized for a fast '386
            machine and my appear lengthy on a slower machine.

                 Using the program should be self explanatory if you
            have a basic understanding of the game. It accepts up to
            four players and will ask for the names. When a single <CR>
            is entered for a name, it uses what names it has up to then
            and plays with that many players.

                 It then asks for the bets. You are given $500.00 to
            start the game and you are not allowed to bet more than the
            remaining amount at any play. When your bankroll drops to
            zero, the play continues without you.

                 When a "?" appears below a hand, it is asking if you
            want a hit. while it is asking, depressing a "1" causes a
            hit while anything else assumes you are done. If you already
            have blackjack, it assumes that you don't want a "hit" and
            skips you. If the dealer has blackjack, all players are
            skipped.

                 When the question mark appears in the lower-left corner
            of the screen, it is asking if you want to continue. An
            <ESC> causes an exit and anything else continues.

                 When the program is first started, it looks for
            extended memory. If none is present, it won't run, otherwise
            it obtains 30 pages. It then draws all the cards, saving
            them in expanded memory. It does this for faster operation.

                 When a blackjack has occurred or when 50 cards have
            been dealt from the deck, a re-shuffle occurs.

                 If you want more information, You will have to get in
            touch with me. The easiest way is to write me at the address
            shown on the copyright notice, otherwise call me at 201-329-
            3216.

                 My graphic/memory-management/mouse/joystick libraries
            are quite extensive and complete. They are Microsoft "C"
            compatible. They are available for sale to all who need
            libraries of this sort.
