DESCRIPTION
Craps is a form of the game of craps that is played in Las
Vegas. The program simulates the roller, while you place
bets. At any time, you may choose 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.
At the start of the game, you have a ``bankroll'' of $2,000.
The program begins prompting with:
bet?
The bet can be all or part of your bankroll. Any bet over
the total bankroll is rejected and the program continues
prompting until a proper bet is made.
Once the bet is accepted, the roller throws the dice. The
following rules apply (you win or lose, 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 fol-
lowing 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, so roll again (Rule 2
applies)
2. On subsequent rolls:
point -- roller wins;
7 -- House wins;
any other number -- roll again.
If you lose your entire bankroll, the House offers to lend
you an additional $2,000. The program prompts as follows:
marker?

A yes (or y) consummates the loan. Any other reply ter-
minates the game.
If you owe the House money, the House reminds you, before
you can place a bet, how many markers are outstanding.
If, at any time, you have outstanding markers and your ban-
kroll exceeds $2,000, the House asks:
Repay marker?
A reply of yes (or y) indicates your willingness to repay
the loan. If only 1 marker is outstanding, the debt is
immediately repaid. However, if more than 1 marker is out-
standing, the House asks:
How many?
markers you want to repay. If you enter an invalid number or
just a carriage return, the program prints an appropriate
message and prompts with
How many?
until you provide a valid number.
If you accumulate 10 markers (a total of $20,000 borrowed
from the House), the program tells you and then exits.
Should your bankroll exceed $50,000, the House automatically
deducts from it the total amount of money needed to pay off
all outstanding markers.
If you accumulate $100,000 or more, you break the bank. The
program then prompts:
New game?
to give the House a chance to win back its money.
The program usually considers any reply other than a yes to
be a no. Exceptions to this are when the program asks you
if you want to place a bet (i.e., bet?) and when it asks how
many markers you want to pay off (i.e., How many?).
To exit, send an interrupt (↑I). Before exiting, the program
tells you whether you 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.
