-# Dice
-#
-# From: BASIC Computer Games (1978)
-#       Edited by David H. Ahl
-#
-# "Not exactly a game, this program simulates rolling
-#  a pair of dice a large number of times and prints out
-#  the frequency distribution.  You simply input the
-#  number of rolls.  It is interesting to see how many
-#  rolls are necessary to approach the theoretical
-#  distribution:
-#
-#  2  1/36  2.7777...%
-#  3  2/36  5.5555...%
-#  4  3/36  8.3333...%
-#    etc.
-#
-# "Daniel Freidus wrote this program while in the
-#  seventh grade at Harrison Jr-Sr High School,
-#  Harrison, New York."
-#
-# Python port by Jeff Jetton, 2019

-# the indices that match the roll values (2 through 12).

-########################################################
-#
-# Porting Notes
-#
-#   A fairly straightforward port.  The only change is
-#   in the handling of the user's "try again" response.
-#   The original program only continued if the user
-#   entered "YES", whereas this version will continue
-#   if any word starting with "Y" or "y" is given.
-#
-#   The instruction text--which, like all these ports,
-#   was taken verbatim from the original listing--is
-#   charmingly quaint in its dire warning against
-#   setting the number of rolls too high.  At the time
-#   of this writing, on a fairly slow computer, a
-#   5000-roll run typically clocks in at well under
-#   1/10 of a second!
-#
-#
-# Ideas for Modifications
-#
-#   Have the results include a third column showing
-#   the percent of rolls each count represents.  Or
-#   (better yet) print a low-fi bar graph using
-#   rows of asterisks to represent relative values,
-#   with each asterisk representing one percent,
-#   for example.
-#
-#   Add a column showing the theoretically expected
-#   percentage, for comparison.
-#
-#   Keep track of how much time the series of rolls
-#   takes and add that info to the final report.
-#
-#   What if three (or four, or five...) dice were
-#   rolled each time?
-#

-# Flip Flop

-# to a row of ten O's:
-# O O O O O O O O O O
-# by typing in a number corresponding
-# to the position of an "X" in the line. On

-# change while on other numbers, two

-# To reset the line to all X's (same
-# game), type 0 (zero). To start a new

-##### Translator Notes:
-I tried to preserve as much of the original layout and flow of the code
-as possible.  However I did use quasi enumerated types for the Fort numbers
-and Fur types.  I think this was certainly a change for the better, and
-makes the code much easier to read.
-
-I program in many different languages on a daily basis.  Most languages
-require brackets around expressions, so I just cannot bring myself to
-write an expression without brackets.  IMHO it makes the code easier to study,
-but it does contravene the Python PEP-8 Style guide.
-
-Interestingly the code seems to have a bug around the prices of Fox Furs.
-The commodity-rate for these is stored in the variable `D1`, however some
-paths through the code do not set this price.  So there was a chance of
-using this uninitialised, or whatever the previous loop set.  I don't
-think this was the original authors intent.  So I preserved the original flow
-of the code (using the previous `D1` value), but also catching the
-uninitialised path, and assigning a "best guess" value.

-//  Despite being a text based game, the code uses simple geometry to simulate a course.
-//  Fairways are 40 yard wide rectangles, surrounded by 5 yards of rough around the perimeter.
-//  The green is a circle of 10 yards radius around the cup.
-//  The cup is always at point (0,0).
-//
-//  Using basic trigonometry we can plot the ball's location using the distance of the stroke and
-//  and the angle of deviation (hook/slice).
-//
-//  The stroke distances are based on real world averages of different club types.
-//  Lots of randomization, "business rules", and luck influence the game play.
-//  Probabilities are commented in the code.
-//
-//  note: 'courseInfo', 'clubs', & 'scoreCard' arrays each include an empty object so indexing
-//  can begin at 1. Like all good programmers we count from zero, but in this context,
-//  it's more natural when hole number one is at index one

-//  Typical green size: 20-30 yards
-//  Typical golf course fairways are 35 to 45 yards wide
-//  Our fairway extends 5 yards past green
-//  Our rough is a 5 yard perimeter around fairway
-//
-//  We calculate the new position of the ball given the ball's point, the distance
-//  of the stroke, and degrees off line (hook or slice).
-//
-//  Degrees off (for a right handed golfer):
-//  Slice: positive degrees = ball goes right
-//  Hook: negative degrees = left goes left
-//
-//  The cup is always at point: 0,0.
-//  We use atan2 to compute the angle between the cup and the ball.
-//  Setting the cup's vector to 0,-1 on a 360 circle is equivalent to:
-//  0 deg = 12 o'clock;  90 deg = 3 o'clock;  180 deg = 6 o'clock;  270 = 9 o'clock
-//  The reverse angle between the cup and the ball is a difference of PI (using radians).
-//
-//  Given the angle and stroke distance (hypotenuse), we use cosine to compute
-//  the opposite and adjacent sides of the triangle, which, is the ball's new position.

-//  Given the large number of combinations needed to describe a particular stroke / ball location,
-//  we use the technique of "bitwise masking" to describe stroke results.
-//  With bit masking, multiple flags (bits) are combined into a single binary number that can be
-//  tested by applying a mask. A mask is another binary number that isolates a particular bit that
-//  you are interested in. You can then apply your language's bitwise opeartors to test or
-//  set a flag.

-#  "In program Guess, the computer  chooses a random

- * Game of Hamurabi
- * 

- * Based on the Basic game of Hamurabi here
- * https://github.com/coding-horror/basic-computer-games/blob/main/43%20Hammurabi/hammurabi.bas
- * 

- * Note:  The idea was to create a version of the 1970's Basic game in Java, without introducing
- * new features - no additional text, error checking, etc has been added.

-# PORTING NOTES:
-#
-# I printed out the BASIC code and hand-annotated what each little block
-# of code did, which feels amazingly retro.
-#
-# I encourage other porters that have a complex knot of GOTOs and
-# semi-nested subroutines to do hard-copy hacking, it might be a
-# different perspective that helps.
-#
-# A spoiler - the objective of the game is not documented, ostensibly to
-# give the human player a challenge. If a player (human or computer)
-# advances a pawn across the board to the far row, that player wins. If
-# a player has no legal moves (either by being blocked, or all their
-# pieces having been captured), that player loses.
-#
-# The original BASIC had 2 2-dimensional tables stored in DATA at the
-# end of the program. This encoded all 19 different board configurations
-# (Hexapawn is a small game), with reflections in one table, and then in
-# a parallel table, for each of the 19 rows, a list of legal moves was
-# encoded by turning them into 2-digit decimal numbers. As gameplay
-# continued, the AI would overwrite losing moves with 0 in the second
-# array.
-#
-# My port takes this "parallel array" structure and turns that
-# information into a small Python class, BoardLayout. BoardLayout stores
-# the board description and legal moves, but stores the moves as (row,
-# column) 2-tuples, which is easier to read. The logic for checking if a
-# BoardLayout matches the current board, as well as removing losing move
-# have been moved into methods of this class.

-THIS PROGRAM PLAYS THE GAME OF HEXAPAWN.
-HEXAPAWN IS PLAYED WITH CHESS PAWNS ON A 3 BY 3 BOARD.
-THE PAWNS ARE MOVED AS IN CHESS - ONE SPACE FORWARD TO
-AN EMPTY SPACE OR ONE SPACE FORWARD AND DIAGONALLY TO
-CAPTURE AN OPPOSING MAN.  ON THE BOARD, YOUR PAWNS
-ARE 'O', THE COMPUTER'S PAWNS ARE 'X', AND EMPTY
-SQUARES ARE '.'.  TO ENTER A MOVE, TYPE THE NUMBER OF
-THE SQUARE YOU ARE MOVING FROM, FOLLOWED BY THE NUMBER
-OF THE SQUARE YOU WILL MOVE TO.  THE NUMBERS MUST BE
-SEPERATED BY A COMMA.
-
-THE COMPUTER STARTS A SERIES OF GAMES KNOWING ONLY WHEN
-THE GAME IS WON (A DRAW IS IMPOSSIBLE) AND HOW TO MOVE.
-IT HAS NO STRATEGY AT FIRST AND JUST MOVES RANDOMLY.
-HOWEVER, IT LEARNS FROM EACH GAME.  THUS, WINNING BECOMES
-MORE AND MORE DIFFICULT.  ALSO, TO HELP OFFSET YOUR
-INITIAL ADVANTAGE, YOU WILL NOT BE TOLD HOW TO WIN THE
-GAME BUT MUST LEARN THIS BY PLAYING.
-
-THE NUMBERING OF THE BOARD IS AS FOLLOWS:
-          123
-          456
-          789
-
-FOR EXAMPLE, TO MOVE YOUR RIGHTMOST PAWN FORWARD,
-YOU WOULD TYPE 9,6 IN RESPONSE TO THE QUESTION
-'YOUR MOVE ?'.  SINCE I'M A GOOD SPORT, YOU'LL ALWAYS

-## Running the code
-
-Assuming the reference [dmd](https://dlang.org/download.html#dmd) compiler:
-```shell
-dmd -dip1000 -run highiq.d
-```
-
-[Other compilers](https://dlang.org/download.html) also exist.

-## Discussion
-
-The original BASIC game code made use of calculus and clever choises of field IDs to determine the validity of moves.
-This is the original layout of IDs over the board:
-
-```
-          13   14   15
-
-          22   23   24
-
-29   30   31   32   33   34   35
-
-38   39   40   41   42   43   44
-
-47   48   49   50   51   52   53
-
-          58   59   60
-
-          67   68   69
-```
-
-This seems not very logical, because, wouldn't it make much more sense to let columns increase with 1 and rows increase
-with 10, so you'd get a consistent coordinate system? It seems that the original author's first step in validating
-moves was to check that moves jumped from one field over another one onto the next. He did this by making sure that
-adjacent IDs alter between even and odd horizontally *and* vertically. So a valid move was always from an even ID to an
-even ID *or* from an odd ID to an odd ID. So one of the checks that the BASIC code made was that the sum of both IDs
-was even. This is of course not a sufficient test, because moves that jump over three fields are illegal. Therefore the
-IDs seem to have been carefully laid oud so that the IDs increase with 1 horizontally, and 9 vertically, everywhere. So
-the only valid difference between IDs for a horizontal move was always 2, and the only valid difference for a vertical
-move was always 18.
-
-Fact of the matter is, however, that checking for difference is sufficient and the even sum rule is superfluous, so
-there is no need for the peculiar distribution of field IDs. Therefore I have chosen the following more logical
-distribution:
-
-```
-          13   14   15
-
-          23   24   25
-
-31   32   33   34   35   36   37
-
-41   42   43   44   45   46   47
-
-51   52   53   54   55   56   57
-
-          63   64   65
-
-          73   74   75
-```
-
-As a consequence, the implementation of the game code has become much simpler; Not alone due to one less check, but due
-to the fact that conversions between IDs and board coordinates have become unnecessary and thus we can work with a single
-representation of the board state.
-
-This version makes a prettier print of the board than the BASIC original, with coordinates for every move, and explains
-illegal moves.
-

-# Life
-
-An implementation of John Conway's popular cellular automaton, also know as **Conway's Game of Life**. The original source was downloaded [from Vintage Basic](http://www.vintage-basic.net/games.html).
-
-Ported by Dyego Alekssander Maas.
-
-## How to run
-
-This program requires you to install [.NET 6 SDK](https://dotnet.microsoft.com/en-us/download/dotnet/6.0). After installed, you just need to run `dotnet run` from this directory in the terminal.
-
-## Know more about Conway's Game of Life
-
-You can find more about Conway's Game of Life on this page of the [Cornell Math Explorers' Club](http://pi.math.cornell.edu/~lipa/mec/lesson6.html), alongside many examples of patterns you can try.
-
-### Optional parameters
-
-Optionally, you can run this program with the `--wait 1000` argument, the number being the time in milliseconds
-that the application will pause between each iteration. This is enables you to watch the simulation unfolding. By default, there is no pause between iterations.
-
-The complete command would be `dotnet run --wait 1000`.
-
-## Entering patterns
-
-Once running the game, you are expected to enter a pattern. This pattern consists of multiple lines of text with either **spaces** or **some character**, usually an asterisk (`*`).
-
-Spaces represent empty cells. Asterisks represent alive cells.
-
-After entering the pattern, you need to enter the word "DONE". It is not case sensitive. An example of pattern would be:
-
-```
- *
-***
-DONE
-```
-
-### Some patterns you could try

-# Game of Life - Java version
-
-Original source downloaded [from Vintage Basic](http://www.vintage-basic.net/games.html)
-
-Conversion to [Oracle Java](https://openjdk.java.net/)
-
-## Requirements
-
-* Requires Java 17 (or later)
-
-## Notes
-
-The Java version of Game of Life tries to mimics the behaviour of the BASIC version.
-However, the Java code does not have much in common with the original.
-
-**Differences in behaviour:**
-* Input supports the ```.``` character, but it's optional.
-* Evaluation of ```DONE``` input string is case insensitive.
-* Run with the ```-s``` command line argument to halt the program after each generation, and continue when ```ENTER``` is pressed.

-# Porting Notes
-#
-#   Not too different from the original, logic-wise. The image was
-#   originally encoded as a series of BASIC "DATA" lines. Here,
-#   we've converted it to a more Pythonic nested list structure.
-#   Other changes include reducing some of the vertical spacing
-#   (since we'll probably be showing this on a screen rather than
-#   the sort of tractor-feed printer the program was written for)
-#   and having the message default to LOVE when no input is given.
-#
-#   This program uses a simple version of run-length encoding to
-#   compress a 60 x 36 image (2,160 characters) into just 252 DATA
-#   values.  That's about an 8.5-to-1 data compression ratio,
-#   which is pretty good!
-#
-#
-# Ideas for Modifications
-#
-#   Process the user's message input to remove spaces and change
-#   to uppercase.
-#
-#   Encode other images in a similar fashion and let the user choose
-#   which one they'd like to use to display their message.
-#
-#   To help with the above step, create a program that reads in a
-#   text file of any sort of similar character/space art and produces
-#   the Python code to initialize the correct nested list of values.
-#
-#   For example, if the input file were:
-#
-#     *****
-#     *  **
-#     **  *
-#
-#   Your program would output:
-#
-#    ((5, ), (1, 1, 2), (2, 1, 1))
-#

-mastermind - Play the game 'Mastermind' from Basic Computer Games
-
-=head1 SYNOPSIS
-
- mastermind.pl
-
-=head1 DETAILS
-
-This Perl script is a port of mastermind, which is the 60th
-entry in Basic Computer Games.
-
-This is pretty much a re-implementation of the BASIC, taking advantage
-of Perl's array functionality and working directly with the alphabetic
-color codes.

-The object of this game is to find four mugwumps
-hidden on a 10 by 10 grid.  Homebase is position 0,0.
-Any guess you make must be two numbers with each
-number between 0 and 9, inclusive.  First number
-is distance to right of homebase and second number
-is distance above homebase.
-
-You get 10 tries.  After each try, I will tell
-you how far you are from each wugwump.

-Solitaire checker puzzle by David Ahl
-
-48 checkers are placed on the 2 outside spaces of a
-standard 64-square checkerboard.  The object is to
-remove as many checkers as possible by diagonal jumps
-(as in standard checkers).  Use the numbered board to
-indicate the square you wish to jump from and to.  On
-the board printed out on each turn '1' indicates a
-checker and '0' an empty square.  When you have no
-possible jumps remaining, input a '0' in response to
-question 'Jump from?'

- one check.pl
-
-=head1 DETAILS
-
-This Perl script is a port of onecheck.
-
-This is a solitaire game played on a checker board, where the object is
-to eliminate as many checkers as possible by making diagonal jumps and
-removing the jumped checkers.
-
-It is pretty much a straight port of the BASIC original.

- * Based on the BASIC game of Orbit here

- * Note:  The idea was to create a version of the 1970's BASIC game in Java, without introducing

-Somewhere above your planet is a Romulan ship.
-
-The ship is in a constant polar orbit.  Its
-distance from the center of your planet is from
-10,000 to 30,000 miles and at its present velocity can
-circle your planet once every 12 to 36 hours.
-
-Unfortunately, they are using a cloaking device so
-you are unable to see them, but with a special
-instrument you can tell how near their ship your
-photon bomb exploded.  You have seven hours until they
-have built up sufficient power in order to escape
-your planet's gravity.
-
-Your planet has enough power to fire one bomb an hour.
-
-At the beginning of each hour you will be asked to give an
-angle (between 0 and 360) and a distance in units of
-100 miles (between 100 and 300), after which your bomb's
-distance from the enemy ship will be given.
-
-An explosion within 5,000 miles of the Romulan ship
-will destroy it.
-
-Below is a diagram to help you visualize your plight.

- * Note:  The idea was to create a version of the 1970's BASIC game in Java, without introducing

-/**
- * Port of CREATIVE COMPUTING Poker written in Commodore 64 Basic to plain Java
- *
- * Original source scanned from magazine: https://www.atariarchives.org/basicgames/showpage.php?page=129
- *
- * I based my port on the OCR'ed source code here: https://github.com/coding-horror/basic-computer-games/blob/main/71_Poker/poker.bas
- *
- * Why? Because I remember typing this into my C64 when I was a tiny little developer and having great fun playing it!
- *
- * Goal: Keep the algorithms and UX more or less as-is; Improve the control flow a bit (no goto in Java!) and rename some stuff to be easier to follow.
- *
- * Result: There are probably bugs, please let me know.

- * Based on the BASIC game of Reverse here

- * Note:  The idea was to create a version of the 1970's BASIC game in Java, without introducing

-reverse.pl - Play the game 'reverse' from Basic Computer Games
-
-=head1 SYNOPSIS
-
- reverse.pl
-
-=head1 DETAILS
-
-This Perl script is a port of C, which is the 73rd entry in
-Basic Computer Games.
-
-The cool thing about this port is the fact that, in a language with
-array slices, list assignments, and a C built-in, the
-reversal is a single assignment statement.

-Conversion to [Perl](https://www.perl.org/)
-
-This conversion consists of three files in `75_Roulette/perl/`:
-
-- `roulette.pl` is the port of the BASIC to Perl;
-- `roulette-test.t` is a Perl test for correctness of display and payout;
-- `make-roulette-test.pl` generates roulette-test.t from roulette.bas.
-
-The ported version of the game numbers the slots from 0 rather than 1, and uses a dispatch table to figure out the payout.
-
-The Perl test loads `roulette.pl` and verifies the Perl slot display and payout logic against the BASIC for all combinations of slots and bets. If any tests fail that fact will be noted at the end of the output.
-
-The test code is generated by reading the BASIC, retaining only the slot display and payout logic (based on line numbers), and wrapping this in code that generates all combinations of bet and spin result. The result is run, and the result is captured and parsed to produce `roulette-test.t`. `make-roulette-test.pl` has some command-line options that may be of interest. `--help` will display the documentation.

-=head1 TITLE
-
-make-roulette-test.pl - Generate the tests for 75_Roulette/perl/roulette.pl
-
-=head1 SYNOPSIS
-
- perl 75_Roulette/perl/make-roulette-test.pl
- perl 75_Roulette/perl/make-roulette-test.pl --program mybasic
- perl 75_Roulette/perl/make-roulette-test.pl --help
- perl 75_Roulette/perl/make-roulette-test.pl --version
-
-=head1 OPTIONS
-
-<<< replace boiler plate >>>
-
-=head2 --help
-
-This option displays the documentation for this script. The script then
-exits.
-
-=head2 --output
-
- --output fubar.t
-
-This option specifies the output file. This needs to be in the same
-directory as F, and defaults to that directory. A single
-dash (C<'-'>) is special-cased to send the output to standard out.
-
-The default is C<--output=test-roulette.t>.
-
-=head2 --program
-
- --program my_basic
-
-This option specifies the name of your BASIC interpreter. This must be
-the name of an executable file in your PATH (aliases do not work).
-
-The default is the first-found in the list C.
-
-=head2 --version
-
-This option displays the version of this script. The script then exits.
-
-=head1 DETAILS
-
-This Perl script generates F, which tests
-F. The latter is expected to be written as a modulino.
-
-This script assumes that:
-
-=over
-
-=item * it is in the same directory as F;
-
-=item * F is in the first-level subdirectory under the current directory;
-
-=back
-
-The generated test assumes that it is in the same directory as
-F.
-
-This script works by abstracting the internals of F and
-wrapping them in a loop that generates all possible spins, and places
-all possible bets on each spin. The generated BASIC is written to a
-temporary file, and executed by a BASIC interpreter. The output is
-parsed and used to generate the output.
-
-Obviously there is some ad-hocery going on, and this script has only
-been tested under C, which was what I had on hand.
-
-B the abstraction process is driven by BASIC line numbers. Any
-change of these puts the ad-hocery at risk.

-The 2:1 bets are:
- 37) 1-12     40) first column
- 38) 13-24    41) second column
- 39) 25-36    42) third column
-
-The even money bets are:
- 43) 1-18     46) odd
- 44) 19-36    47) red
- 45) even     48) black
-
- 49) 0 and 50) 00 pay off 35:1
- Note: 0 and 00 do not count under any
-       bets except their own.
-
-When I ask for each bet, type the number
-and the amount, separated by a comma.
-For example: to bet $500 on black, type 48,500
-when I ask for a bet.
-
-The minimum bet is $5, the maximum is $500.

-=head1 TITLE
-
-roulette - Play the game 'Roulette' from Basic Computer Games
-
-=head1 SYNOPSIS
-
- roulette.pl
-
-=head1 DETAILS
-
-This Perl script is a port of roulette, which is the 75th
-entry in Basic Computer Games.
-
-The main internal changes are converting the roulette slot numbering to
-0-based and replacing most of the payout logic with a dispatch table.
-These changes were tested for correctness against the original BASIC.

-# Russian Roulette
-#
-# From Basic Computer Games (1978)
-#
-#    In this game, you are given by the computer a
-#   revolver loaded with one bullet and five empty
-#   chambers. You spin the chamber and pull the trigger
-#   by inputting a "1", or, if you want to quit, input
-#   a "2". You win if you play ten times and are still
-#   alive.
-#    Tom Adametx wrote this program while a student at
-#   Curtis Jr. High School in Sudbury, Massachusetts.

-# Porting Notes
-#
-#    Altough the description says that accepts "1" or "2",
-#   the original game accepts any number as input, and
-#   if it's different of "2" the program considers
-#   as if the user had passed "1". That feature was
-#   kept in this port.
-#    Also, in the original game you must "pull the trigger"
-#   11 times instead of 10 in orden to win,
-#   given that N=0 at the beginning and the condition to
-#   win is "IF N > 10 THEN  80". That was fixed in this
-#   port, asking the user to pull the trigger only ten
-#   times, tough the number of round can be set changing
-#   the constant NUMBER_OF_ROUNDS.

-# From: BASIC Computer Games (1978)

-#
-# "Did you ever go to a computer show and see a bunch of
-#  CRT terminals just sitting there waiting forlornly
-#  for someone to give a demo on them.  It was one of
-#  those moments when I was at DEC that I decided there
-#  should be a little bit of background activity.  And
-#  why not plot with words instead of the usual X's?
-#  Thus SINE WAVE was born and lives on in dozens of
-#  different versions.  At least those CRTs don't look
-#  so lifeless anymore."

-#
-# Porting Notes
-#
-#   The original BASIC version hardcoded two words in
-#   the body of the code and then used a sentinel flag
-#   (flipping between 0 and 1) with IF statements to
-#   determine the word to display next.
-#
-#   Here, the words have been moved to a Python tuple,
-#   which is iterated over without any assumptions about
-#   how long it is.  The STRINGS tuple can therefore be
-#   modified to have to program print out any sequence
-#   of any number of lines of text.
-#
-#   Since a modern computer running Python will print
-#   to the screen much more quickly than a '70s-era
-#   computer running BASIC would, a delay component
-#   has been introduced in this version to make the
-#   output more historically accurate.
-#
-#
-# Ideas for Modifications
-#
-#   Ask the user for desired number of lines (perhaps

-# Slots
-#
-# From Basic Computer Games (1978)
-#
-#    "The slot machine or one-arm bandit is a mechanical
-#   device that will absorb coins just about as fast as
-#   you can feed it. After inserting a coin, you pull a
-#   handle that sets three indepent reels spining. If the
-#   reels stop with certain symbols appearing in the pay
-#   line, you get a certain payoff. The original slot
-#   machine, called the Liberty bell, was invented in 1895
-#   by Charles Fey in San Francisco. Fey refused to sell
-#   or lease the manufacturing rights, so H.S. Mills in
-#   Chicago built a similar, but much improved, machine
-#   called the Operators Bell. This has survived nearly
-#   unchanged to today.
-#     On the operators Bell and other standard slot
-#   machines, there are 20 symbols on each wheel but they
-#   are not distributed evenly among the objects(cherries,
-#   bar, apples, etc). Of the 8000 possible combinations,
-#   the expected payoff(to the player) is 7049 or $89.11
-#   for every $100.00 put in, one of the lowest expected
-#   payoffs of all casino games.
-#     In the program here, the payoff is considerably more
-#   liberal; indeed it appears to favor the player by 11%
-#   -- i.e., an expected payoff of $111 for each $100 bet."
-#     The program was originally written by Fred Mirabelle
-#   and Bob Harper

-/**
- * SPLAT simulates a parachute jump in which you try to open your parachute at the last possible moment without going
- * splat! You may select your own terminal velocity or let the computer do it for you. You many also select the
- * acceleration due to gravity or, again, let the computer do it in which case you might wind up on any of eight
- * planets (out to Neptune), the moon, or the sun.
- * 

- * The computer then tells you the height you’re jumping from and asks for the seconds of free fall. It then divides
- * your free fall time into eight intervals and gives you progress reports on your way down. The computer also keeps
- * track of all prior jumps in the array A and lets you know how you compared with previous successful jumps. If you
- * want to recall information from previous runs, then you should store array A in a disk or take file and read it
- * before each run.
- * 

- * John Yegge created this program while at the Oak Ridge Associated Universities.
- * 

- * Ported from BASIC by jason plumb (@breedx2)

-SPLAT
-
-Splat similates a parachute jump in which you try to open your parachute
-at the last possible moment without going splat! You may select your own
-terminal velocity or let the computer do it for you. You may also select
-the acceleration due to gravity or, again, let the computer do it
-in which case you might wind up on any one of the eight planets (out to
-Neptune), the moon, or the sun.
-
-The computer then tells you the height you're jumping from and asks for
-the seconds of free fall. It then divides your free fall time into eight
-intervals and gives you progress reports on the way down. The computer
-also keeps track of all prior jumps and lets you know how you compared
-with previous successful jumps. If you want to recall information from
-previous runs, then you should store the array `successful_jumps` on
-disk and read it before each run.
-
-John Yegge created this program while at the Oak Ridge Associated
-Universities.

-Stars

-From: BASIC Computer Games (1978)
-      Edited by David H. Ahl
-
-"In this game, the computer selects a random number from 1 to 100
- (or any value you set [for MAX_NUM]).  You try to guess the number
- and the computer gives you clues to tell you how close you're
- getting.  One star (*) means you're far away from the number; seven
- stars (*******) means you're really close.  You get 7  guesses.
-
-"On the surface this game is very similar to GUESS; however, the
- guessing strategy is quite different.  See if you can come up with
- one or more approaches to finding the mystery number.
-
-"Bob Albrecht of People's Computer Company created this game."

-# Porting Notes
-#
-#   The original program never exited--it just kept playing rounds
-#   over and over.  This version asks to continue each time.
-#
-#
-# Ideas for Modifications
-#
-#   Let the player know how many guesses they have remaining after
-#   each incorrect guess.
-#
-#   Ask the player to select a skill level at the start of the game,
-#   which will affect the values of MAX_NUM and MAX_GUESSES.
-#   For example:
-#
-#       Easy   = 8 guesses, 1 to 50
-#       Medium = 7 guesses, 1 to 100
-#       Hard   = 6 guesses, 1 to 200

-      INSTRUCTIONS FOR 'SUPER STAR TREK'
-
-1. When you see "Command ?" printed, enter one of the legal
-     commands (NAV, SRS, LRS, PHA, TOR, SHE, DAM, COM, OR XXX).
-2. If you should type in an illegal command, you'll get a short
-     list of the legal commands printed out.
-3. Some commands require you to enter data (for example, the
-     'NAV' command comes back with 'Course (1-9) ?'.)  If you
-     type in illegal data (like negative numbers), then command
-     will be aborted.
-
-     The galaxy is divided into an 8 X 8 quadrant grid,
-and each quadrant is further divided into an 8 X 8 sector grid.
-
-     You will be assigned a starting point somewhere in the
-galaxy to begin a tour of duty as commander of the starship
-Enterprise; your mission: to seek and destroy the fleet of
-Klingon warships which are menacing the United Federation of
-Planets.
-
-     You have the following commands available to you as captain
-of the starship Enterprise:
-
-NAV command = Warp Engine Control
-     Course is in a circular numerical      4  3  2
-     vector arrangement as shown             . . .
-     integer and real values may be           ...
-     used.  (Thus course 1.5 is half-     5 ---*--- 1
-     way between 1 and 2.                     ...
-                                             . . .
-     Values may approach 9.0, which         6  7  8
-     itself is equivalent to 1.0
-                                            COURSE
-     One warp factor is the size of
-     one quadrant.  Therefore, to get
-     from quadrant 6,5 to 5,5, you WOULD
-     use course 3, warp factor 1.
-
-SRS command = Short Range Sensor Scan
-     Shows you a scan of your present quadrant.
-
-     Symbology on your sensor screen is as follows:
-        <*> = Your starship's position
-        +K+ = Klingon battle cruiser
-        >!< = Federation starbase (refuel/repair/re-arm here!)
-         *  = Star
-
-     A condensed 'status report' will also be presented.
-
-LRS command = Long Range Sensor Scan
-     Shows conditions in space for one quadrant on each side
-     of the Enterprise (which is in the middle of the scan).
-     The scan is coded in the form ###, where the units digit
-     is the number of stars, the tens digit is the number of
-     starbases, and the hundreds digit is the number of
-     Klingons.
-
-     Example - 207 = 2 Klingons, No starbases, & 7 stars.
-
-PHA command = Phaser Control
-     Allows you to destroy the Klingon battle cruisers by
-     zapping them with suitably large units of energy to
-     deplete their shield power.  (Remember, Klingons have
-     phasers, too!)
-
-TOR command = Photon Torpedo Control
-     Torpedo course is the same as used in warp engine control.
-     If you hit the Klingon vessel, he is destroyed and
-     cannot fire back at you.  If you miss, you are subject to
-     his phaser fire.  In either case, you are also subject to
-     the phaser fire of all other Klingons in the quadrant.
-
-     The library-computer (COM command) has an option to
-     compute torpedo trajectory for you (Option 2).
-
-SHE command = Shield Control
-     Defines the number of energy units to be assigned to the
-     shields.  Energy is taken from total ship's energy.  Note
-     that the status display total energy includes shield energy.
-
-DAM command = Damage Control Report
-     Gives the state of repair of all devices.  Where a negative
-     'state of repair' shows that the device is temporarily
-     damaged.
-
-COM command = Library-Computer
-     The library-computer contains six options:
-     Option 0 = Cumulative Galactic Record
-        This option shows computer memory of the results of all
-        previous short and long range sensor scans.
-     Option 1 = Status Report
-        This option shows the number of Klingons, Stardates,
-        and starbases remaining in the game.
-     Option 2 = Photon Torpedo Data
-        Which gives directions and distance from the Enterprise
-        to all Klingons in your quadrant.
-     Option 3 = Starbase Nav Data
-        This option gives direction and distance to any
-        starbase within your quadrant.
-     Option 4 = Direction/Distance Calculator
-        This option allows you to enter coordinates for
-        direction/distance calculations.
-     Option 5 = Galactic Region Name Map
-        This option prints the names of the sixteen major
-        galactic regions referred to in the game.

-      INSTRUCTIONS FOR 'SUPER STAR TREK'
-
-1. WHEN YOU SEE \COMMAND ?\ PRINTED, ENTER ONE OF THE LEGAL
-     COMMANDS (NAV,SRS,LRS,PHA,TOR,SHE,DAM,COM, OR XXX).
-
-2. IF YOU SHOULD TYPE IN AN ILLEGAL COMMAND, YOU'LL GET A SHORT
-     LIST OF THE LEGAL COMMANDS PRINTED OUT.
-
-3. SOME COMMANDS REQUIRE YOU TO ENTER DATA (FOR EXAMPLE, THE
-     'NAV' COMMAND COMES BACK WITH 'COURSE (1-9) ?'.)  IF YOU
-     TYPE IN ILLEGAL DATA (LIKE NEGATIVE NUMBERS), THAN COMMAND
-     WILL BE ABORTED
-     THE GALAXY IS DIVIDED INTO AN 8 X 8 QUADRANT GRID,
-AND EACH QUADRANT IS FURTHER DIVIDED INTO AN 8 X 8 SECTOR GRID.
-     YOU WILL BE ASSIGNED A STARTING POINT SOMEWHERE IN THE
-GALAXY TO BEGIN A TOUR OF DUTY AS COMANDER OF THE STARSHIP
-\ENTERPRISE\; YOUR MISSION: TO SEEK AND DESTROY THE FLEET OF
-KLINGON WARWHIPS WHICH ARE MENACING THE UNITED FEDERATION OF
-PLANETS.
-
-     YOU HAVE THE FOLLOWING COMMANDS AVAILABLE TO YOU AS CAPTAIN
-OF THE STARSHIP ENTERPRISE:
-
-\NAV\ COMMAND = WARP ENGINE CONTROL --
-     COURSE IS IN A CIRCULAR NUMERICAL      4  3  2
-     VECTOR ARRANGEMENT AS SHOWN             . . .
-     INTEGER AND REAL VALUES MAY BE           ...
-     USED.  (THUS COURSE 1.5 IS HALF-     5 ---*--- 1
-     WAY BETWEEN 1 AND 2                      ...
-                                             . . .
-     VALUES MAY APPROACH 9.0, WHICH         6  7  8
-     ITSELF IS EQUIVALENT TO 1.0"
-                                            COURSE
-     ONE WARP FACTOR IS THE SIZE OF
-     ONE QUADTANT.  THEREFORE, TO GET
-     FROM QUADRANT 6,5 TO 5,5, YOU WOULD
-     USE COURSE 3, WARP FACTOR 1.
-
-\SRS\ COMMAND = SHORT RANGE SENSOR SCAN
-     SHOWS YOU A SCAN OF YOUR PRESENT QUADRANT.
-     SYMBOLOGY ON YOUR SENSOR SCREEN IS AS FOLLOWS:
-        <*> = YOUR STARSHIP'S POSITION
-        +K+ = KLINGON BATTLE CRUISER
-        >!< = FEDERATION STARBASE (REFUEL/REPAIR/RE-ARM HERE!)
-         *  = STAR
-     A CONDENSED 'STATUS REPORT' WILL ALSO BE PRESENTED.
-
-\LRS\ COMMAND = LONG RANGE SENSOR SCAN
-     SHOWS CONDITIONS IN SPACE FOR ONE QUADRANT ON EACH SIDE
-     OF THE ENTERPRISE (WHICH IS IN THE MIDDLE OF THE SCAN)
-     THE SCAN IS CODED IN THE FORM \###\, WHERE TH UNITS DIGIT
-     IS THE NUMBER OF STARS, THE TENS DIGIT IS THE NUMBER OF
-     STARBASES, AND THE HUNDRESDS DIGIT IS THE NUMBER OF
-     KLINGONS.
-     EXAMPLE - 207 = 2 KLINGONS, NO STARBASES, & 7 STARS.
-
-\PHA\ COMMAND = PHASER CONTROL.
-     ALLOWS YOU TO DESTROY THE KLINGON BATTLE CRUISERS BY
-     ZAPPING THEM WITH SUITABLY LARGE UNITS OF ENERGY TO
-     DEPLETE THEIR SHIELD POWER.  (REMBER, KLINGONS HAVE
-     PHASERS TOO!)
-
-\TOR\ COMMAND = PHOTON TORPEDO CONTROL
-     TORPEDO COURSE IS THE SAME AS USED IN WARP ENGINE CONTROL
-     IF YOU HIT THE KLINGON VESSEL, HE IS DESTROYED AND
-     CANNOT FIRE BACK AT YOU.  IF YOU MISS, YOU ARE SUBJECT TO
-     HIS PHASER FIRE.  IN EITHER CASE, YOU ARE ALSO SUBJECT TO
-     THE PHASER FIRE OF ALL OTHER KLINGONS IN THE QUADRANT.
-     THE LIBRARY-COMPUTER (\COM\ COMMAND) HAS AN OPTION TO
-     COMPUTE TORPEDO TRAJECTORY FOR YOU (OPTION 2)
-
-\SHE\ COMMAND = SHIELD CONTROL
-     DEFINES THE NUMBER OF ENERGY UNITS TO BE ASSIGNED TO THE

-     OPTION 1 = STATUS REPORT
-        THIS OPTION SHOWS THE NUMBER OF KLINGONS, STARDATES,
-        AND STARBASES REMAINING IN THE GAME.
-     OPTION 2 = PHOTON TORPEDO DATA
-        WHICH GIVES DIRECTIONS AND DISTANCE FROM THE ENTERPRISE
-        TO ALL KLINGONS IN YOUR QUADRANT
-     OPTION 3 = STARBASE NAV DATA
-        THIS OPTION GIVES DIRECTION AND DISTANCE TO ANY
-        STARBASE WITHIN YOUR QUADRANT
-     OPTION 4 = DIRECTION/DISTANCE CALCULATOR
-        THIS OPTION ALLOWS YOU TO ENTER COORDINATES FOR
-        DIRECTION/DISTANCE CALCULATIONS
-     OPTION 5 = GALACTIC /REGION NAME/ MAP
-        THIS OPTION PRINTS THE NAMES OF THE SIXTEEN MAJOR

-# Synonym
-#
-# From Basic Computer Games (1978)
-#
-# A synonym of a word is another word (in the English language) which has the same,
-# or very nearly the same, meaning. This program tests your knowledge of synonyms
-# of a few common words.
-#
-# The computer chooses a word and asks you for a synonym. The computer then tells
-# you whether you’re right or wrong. If you can’t think of a synonym, type “HELP”
-# which causes a synonym to be printed.
-# You may put in words of your choice in the data statements.
-# The number following DATA in Statement 500 is the total number of data statements.
-# In each data statement, the first number is the number of words in that statement.
-#
-# Can you think of a way to make this into a more general kind of CAI program for any subject?
-# Walt Koetke of Lexington High School, Massachusetts created this program.

-You are the weapons officer on the Starship Enterprise
-and this is a test to see how accurate a shot you
-are in a three-dimensional range.  You will be told
-the radian offset for the X and Z axes, the location
-of the target in three dimensional rectangular coordinates,
-the approximate number of degrees from the X and Z
-axes, and the approximate distance to the target.
-You will then proceed to shoot at the target until it is
-destroyed!
-
-Good luck!!

- * Note:  The idea was to create a version of the 1970's BASIC game in Java, without introducing

- * Note:  The idea was to create a version of the 1970's BASIC game in Java, without introducing

-Original source downloaded from [Vintage Basic](http://www.vintage-basic.net/games.html)
-
-Converted to [D](https://dlang.org/) by [Bastiaan Veelo](https://github.com/veelo).
-
-The Basic original required words to be exactly five letters in length for the program to behave correctly.
-This version does not replicate that limitation, and the test for that requirement is commented out.
-
-## Running the code
-
-Assuming the reference [dmd](https://dlang.org/download.html#dmd) compiler:
-```shell
-dmd -dip1000 -run word.d
-```
-
-[Other compilers](https://dlang.org/download.html) also exist.

- * Based on the BASIC game of Word here
- * https://github.com/coding-horror/basic-computer-games/blob/main/96%20Word/word.bas

- * Note:  The idea was to create a version of the 1970's BASIC game in Java, without introducing
