      NAME
           craps - the game of craps

      SYNTAX

      DESCRIPTION
           Craps is a form of the game of craps that is played in Las
           Vegas.  The program simulates the roller, while the user
           (the player) places bets.  The player may choose, at any
           time, to bet with the roller or with the House.  A bet of a
           negative amount is taken as a bet with the House, any other
           bet is a bet with the roller.

           The player starts off with a ``bankroll'' of $2,000.

           The program prompts with:

                bet?

           The bet can be all or part of the player's bankroll.  Any
           bet over the total bankroll is rejected and the program
           prompts with bet? until a proper bet is made.

           Once the bet is accepted, the roller throws the dice.  The
           following rules apply (the player wins or loses depending on
           whether the bet is placed with the roller or with the House;
           the odds are even).  The first roll is the roll immediately
           following a bet:

                1. On the first roll:

                       7 or 11            wins for the roller;
                       2, 3, or 12        wins for the House;
                       any other number   is the point, roll again
                                          (Rule 2 applies).

                2. On subsequent rolls:
                       point              roller wins;
                       7                  House wins;
                       any other number   roll again.

           If a player loses the entire bankroll, the House will offer
           to lend the player an additional $2,000.  The program will
           prompt:

                marker?

           A yes (or y) consummates the loan.  Any other reply
           terminates the game.

           If a player owes the House money, the House reminds the

           player, before a bet is placed, how many markers are
           outstanding.

           If, at any time, the bankroll of a player who has
           outstanding markers exceeds $2,000, the House asks:

                Repay marker?

           A reply of yes (or y) indicates the player's willingness to
           repay the loan.  If only 1 marker is outstanding, it is
           immediately repaid.  However, if more than 1 marker are
           outstanding, the House asks:

                How many?

           markers the player would like to repay.  If an invalid
           number is entered (or just a carriage return), an
           appropriate message is printed and the program will prompt
           with How many? until a valid number is entered.

           If a player accumulates 10 markers (a total of $20,000
           borrowed from the House), the program informs the player of
           the situation and exits.

           Should the bankroll of a player who has outstanding markers
           exceed $50,000, the total amount of money borrowed will be
           automatically repaid to the House.

           Any player who accumulates $100,000 or more breaks the bank.
           The program then prompts:

                New game?

           to give the House a chance to win back its money.

           Any reply other than yes is considered to be a no (except in
           the case of bet? or How many?).  To exit, send an interrupt
           (break), DEL, or control-D.  The program will indicate
           whether the player won, lost, or broke even.

      MISCELLANEOUS
           The random number generator for the die numbers uses the
           seconds from the time of day.  Depending on system usage,
           these numbers, at times, may seem strange but occurrences of
           this type in a real dice situation are not uncommon.
