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).
Two versions are supplied that are functionally equivalent, but differ in source layout:
<dl>
<dt><tt>aceyducey_literal.d</tt></dt>
<dd>A largely literal transcription of the original Basic source. All unnecessary uglyness is preserved.</dd>
<dt><tt>aceyducey.d</tt></dt>
<dd>An idiomatic D refactoring of the original, with a focus on increasing the readability and robustness.
Memory-safety <A href="https://dlang.org/spec/memory-safe-d.html">is ensured by the language</a>, thanks to the
<tt>@safe</tt> annotation.</dd>
</dl>
## Running the code
Assuming the reference [dmd](https://dlang.org/download.html#dmd) compiler:
```shell
dmd -run aceyducey.d
```
[Other compilers](https://dlang.org/download.html) also exist.
Note that there are compiler switches related to memory-safety (`-preview=dip25` and `-preview=dip1000`) that are not
used here because they are unnecessary in this case. What these do is to make the analysis more thorough, so that with
them some code that needed to be `@system` can then be inferred to be in fact `@safe`. [Code that compiles without
these switches is just as safe as when compiled with them]
(https://forum.dlang.org/post/dftgjalswvwfjpyushgn@forum.dlang.org).

=head1 TITLE
animal.pl - Play the game 'animal' from Basic Computer Games
=head1 SYNOPSIS
animal.pl
=head1 DETAILS
This Perl script is a port of C<animal>, which is the 3ed entry in Basic
Computer Games.
The original BASIC was greatly complicated by the need to emulate a
binary tree with an array. The implementation using hashes as nodes in
an actual binary tree is much simpler.

@@ -8,6 +8,28 @@ The money system is Rollods; each person needs 100 Rallods per year to survive.
The author of this program is James A. Storer who wrote it while a student at Lexington High School.
## Bugs
Implementers should be aware that this game contains at least one bug.
On basic line 1450
1450 V3=INT(A+V3)
1451 A=INT(A+V3)
...where A is the current treasury, and V3 is initially zero.
This would mean that the treasury doubles at the end of the first year, and all calculations for an increase in the treasury due to tourism are discarded.
Possibly, this made the game more playable, although impossible for the player to understand why the treasury was increasing?
A quick fix for this bug in the original code would be
1450 V3=ABS(INT(V1-V2))
1451 A=INT(A+V3)

to do is arrange a list of numbers (1 through @{[ NUMBER_OF_NUMBERS ]})

tell me how many numbers (counting from the left) to
reverse. For example, if the current list is:

=head1 TITLE
reverse.pl - Play the game 'reverse' from Basic Computer Games
=head1 SYNOPSIS
reverse.pl
=head1 DETAILS
This Perl script is a port of C<reverse>, 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<reverse()> built-in, the
reversal is a single assignment statement.
