The adventure game is called Nani Search. Next, create a new source file.

We can illustrate this at the highest level. Each is defined by its name and a number called arity. Jargon With any field of knowledge, the critical concepts of the field are embedded in the definitions of its technical terms. The Prolog program is composed of predicates procedures, record types, relations.

Notice the order of the symbols in the greater or equal than and less than or equal operators. The terrifying obstacle between you and success is a dark room. The arguments should be customer, item, and quantity. Almost every concept in Prolog can be referred to by synonymous terms.

Note that the syntax of calling the report code is the same as the syntax used for posing the purely logical queries. We can’t expect the user to type the name in quotes. The listener interactions are distinguished by the presence of the question mark and dash?


With any field of knowledge, the critical concepts of the field are embedded in the definitions of its technical terms.

Programming in Prolog is significantly different from conventional procedural programming proog requires a readjustment in the way one thinks about programming.

Let’s look at the simple example in more detail. Go back to the edit window and add the line. It is getting late and you’re tired, but you can’t go to sleep without your nani.

Loading the source code in the Listener is called consulting. Prolog is no exception.

It is getting’ ,nl, write ‘late and you”re tired, but you can”t tutirial to sleep’ ,nl, write ‘without your Nani. Prolog must be able to handle arithmetic in order to be a useful general purpose programming language.

Enter this query in the listener. Puzzle is only called from goto for this reason. This message is followed by the typical listener prompt. The following example illustrates a Prolog program that prints a report of all the known mortals.

The adventure game is a good example since it contains mundane programming constructs, symbolic reasoning, natural language, data, and logic. Then select File Save from the menu. Select File New File, and enter the name of your file, ‘mortal. The arity is the fixed number of arguments attributes, fields the predicate has. azi

Then we will implement the commands that manipulate the logicbase. For example, at the highest level we have a Prolog program logicbase. It allows for more rapid development and prototyping than most languages because it tutorkal semantically close to the logical specification of a program. It leads to pgolog that is easier to write and easier to maintain.


The tuforial can be added and tested separately in a Prolog program, which makes it possible to incrementally develop the applications described in the book. Once you’ve loaded the program, try the following Prolog queries. Enter the pro-gram in the edit window, paying careful attention to upper and lowercase letters and punctuation. One is code, meant to be entered in a source file, and the other is interactions with the listener.

If you forget the period and mazi probably willyou can enter it on the next line with a ‘return. As with any language, the best way to learn Prolog is to use it. The Nani is your security blanket. Logic Programming Let’s look at the simple example in more detail.

You should now be able to create and edit amzk files for Prolog, and be able to load and use them from a Prolog listener. Its syntax calls for the use of operators, which will be described in more detail in chapter When you understand terms such as predicateclausebacktrackingand unification you will have a good grasp of Prolog.
