# Animal
#
# From: Basic computer Games(1978)
#
# Unlike other computer games in which the computer
# picks a number or letter and you must guess what it is,
# in this game you think of an animal and the computer asks
# you questions and tries to guess the name of your animal.
# If the computer guesses incorrectly, it will ask you for a
# question that differentiates the animal it guessed
# from the one you were thinking of. In this way the
# computer "learns" new animals. Questions to differentiate
# new animals should be input without a question mark.
# This version of the game does not have a SAVE feature.
# If your sistem allows, you may modify the program to
# save array A$, then reload the array when you want
# to play the game again. This way you can save what the
# computer learns over a series of games.
# At any time if you reply 'LIST' to the question "ARE YOU
# THINKING OF AN ANIMAL", the computer will tell you all the
# animals it knows so far.
# The program starts originally by knowing only FISH and BIRD.
# As you build up a file of animals you should use broad,
# general questions first and then narrow down to more specific
# ones with later animals. For example, If an elephant was to be
# your first animal, the computer would ask for a question to distinguish
# an elephant from a bird. Naturally there are hundreds of possibilities,
# however, if you plan to build a large file of animals a good question
# would be "IS IT A MAMAL".
# This program can be easily modified to deal with categories of
# things other than animals by simply modifying the initial data
# in Line 530 and the dialogue references to animal in Lines 10,
# 40, 50, 130, 230, 240 and 600. In an educational environment, this
# would be a valuable program to teach the distinguishing chacteristics

Animal
From: Basic computer Games(1978)
Unlike other computer games in which the computer
picks a number or letter and you must guess what it is,
in this game you think of an animal and the computer asks
you questions and tries to guess the name of your animal.
If the computer guesses incorrectly, it will ask you for a
question that differentiates the animal it guessed
from the one you were thinking of. In this way the
computer "learns" new animals. Questions to differentiate
new animals should be input without a question mark.
This version of the game does not have a SAVE feature.
If your sistem allows, you may modify the program to
save array A$, then reload the array when you want
to play the game again. This way you can save what the
computer learns over a series of games.
At any time if you reply 'LIST' to the question "ARE YOU
THINKING OF AN ANIMAL", the computer will tell you all the
animals it knows so far.
The program starts originally by knowing only FISH and BIRD.
As you build up a file of animals you should use broad,
general questions first and then narrow down to more specific
ones with later animals. For example, If an elephant was to be
your first animal, the computer would ask for a question to distinguish
an elephant from a bird. Naturally there are hundreds of possibilities,
however, if you plan to build a large file of animals a good question
would be "IS IT A MAMAL".
This program can be easily modified to deal with categories of
things other than animals by simply modifying the initial data
in Line 530 and the dialogue references to animal in Lines 10,
40, 50, 130, 230, 240 and 600. In an educational environment, this
would be a valuable program to teach the distinguishing chacteristics
of many classes of objects -- rock formations, geography, marine life,
cell structures, etc.
