Introduction
What is Prolog?
Prolog is an acronym for PROgramming in LOGic. It is a declarative language that was developed in the 1970s as a tool for AI research and applications. Unlike imperative languages such as C or Java, where you have to specify how to solve a problem step by step, in Prolog you only have to describe what the problem is and what the solution should look like using logical facts and rules. Prolog then uses a technique called logical inference to find all possible solutions that satisfy your description.
For example, suppose you want to write a program that can tell you who are the parents of a given person in a family tree. In Prolog, you can simply write something like this:
parent(john, mary). parent(mary, alice). parent(mary, bob). parent(bob, carol). ?- parent(X, bob). X = mary. ?- parent(john, Y). Y = mary.
The first four lines are facts that state who are the parents of whom. The last two lines are queries that ask who are the parents of Bob and who are the children of John. The answers are given by Prolog using logical inference based on the facts.
What is WIN-PROLOG?
WIN-PROLOG is the leading Prolog compiler system for Windows-based PCs. It was developed by Logic Programming Associates Ltd (LPA), a company that specializes in logic-based software development tools and solutions. WIN-PROLOG allows you to write, compile, debug, and run Prolog programs on your Windows machine with ease and efficiency. It also provides a graphical user interface (GUI) that lets you interact with your programs using menus, buttons, dialogs, graphics, etc.
WIN-PROLOG supports various extensions and enhancements to the standard Prolog language, such as object-oriented programming (Prolog++), expert systems development (flex), constraint logic programming (Flint), case-based reasoning (CBR Toolkit), data mining (Data Mining Toolkit), web development (WebFlex Toolkit), etc. It also comes with a rich set of built-in tools and libraries that cover various domains such as natural language processing, database access, XML processing, neural networks, genetic algorithms, etc.
What is LPA WIN-PROLOG 4.9.rar?
LPA WIN-PROLOG 4.9.rar is a compressed file that contains the latest version of WIN-PROLOG (version 8.0) along with its documentation and examples. It is available for download from LPA's website or from other online sources. The file size is about 16 MB and it can be extracted using any software that supports RAR format.
LPA WIN-PROLOG 4.9.rar is compatible with all versions of Windows from XP to 10, both 32-bit and 64-bit systems. It requires at least 512 MB of RAM and 100 MB of disk space.
Features of WIN-PROLOG 8.0
Brand new 64-bit version
In 2018, LPA released a brand new 64-bit version of WIN-PROLOG alongside the classic 32-bit version. The 64-bit version can take advantage of the larger memory space and faster processing power of modern computers, allowing you to handle larger and more complex problems with ease.
The 64-bit version is identical to the 32-bit version in terms of functionality and syntax, so you don't have to worry about compatibility issues or learning curves. You can switch between them seamlessly depending on your needs and preferences.
Native x87 floating point package
A brand new high-precision floating point maths package was written for WIN-PROLOG 5.0 to replace the previously-used emulation library that had been used since the earliest days of WIN-PROLOG. The new package is faster, more accurate, and has been extensively tested for over a year to ensure its integrity and reliability.
The new package supports all standard arithmetic operations (+,-,\*,/,^), trigonometric functions (sin, cos, tan, etc.), logarithmic functions (log, exp), hyperbolic functions (sinh, cosh), special functions (gamma, beta), complex numbers (realpart, imagpart), etc.
Multi-touch support
In response to the advent of Windows 8 and multi-touch tablet computers, WIN-PROLOG includes support for multi-touch screens: in future releases, multi-touch will be incorporated into the GUI of WIN-PROLOG's graphical toolkits, such as VisiRule; meanwhile, one example program has been included to demonstrate the use of graphics, touch messages and MIDI support to implement a playable, fully polyphonic on-screen "piano".
Musical Instrument Digital Interface (MIDI)
Comprehensive support for the Musical Instrument Digital Interface (MIDI) opens up a whole new world of experimental research and analysis of music, something to which Prolog's inherent pattern matching is well suited. Not only can MIDI sequences be captured and replayed in real time, but special low-level timers and message handlers mean that WIN-PROLOG programs can perform sophisticated transformations and complex manipulations of musical data and system exclusive dumps without interrupting or affecting the accuracy of recording and playback.

How to use WIN-PROLOG 8.0
Creating and running a Prolog program
To create a Prolog program in WIN-PROLOG, you need to use a text editor such as Notepad or WordPad to write your facts and rules in a plain text file with a .pl extension. For example, you can create a file called family.pl that contains the following code:
parent(john, mary). parent(mary, alice). parent(mary, bob). parent(bob, carol).
To run your Prolog program in WIN-PROLOG, you need to load it into the Prolog engine using the consult command. For example, you can type the following command in the Console Window:
?- consult('family.pl').
This will load your program into memory and display a message like this:
family.pl compiled 0.00 sec yes
Now you can ask queries about your program using the ?- prompt. For example, you can type:
?- parent(X, bob). X = mary.
This will display one possible answer to your query and wait for your input. You can press ; to see more answers or . to end the query. For example:
?- parent(X, bob). X = mary ; no
Using the graphical user interface (GUI)
WIN-PROLOG also provides a graphical user interface (GUI) that lets you interact with your programs using menus, buttons, dialogs, graphics, etc. The GUI consists of several windows that perform different functions:
The Console Window is where you can type commands and queries to the Prolog engine.
The Editor Window is where you can edit your Prolog programs using syntax highlighting and indentation.
The Trace Window is where you can debug your programs using single-stepping and breakpoints.
The Graphics Window is where you can display graphics using Prolog predicates.
The Menu Window is where you can access various tools and options using menus.
You can switch between these windows using the mouse or keyboard shortcuts. You can also resize, move, minimize, maximize, or close these windows as you wish.
Using the built-in tools and libraries
WIN-PROLOG comes with a rich set of built-in tools and libraries that cover various domains such as natural language processing, database access, XML processing, neural networks, genetic algorithms, etc. You can use these tools and libraries to enhance your programs and solve more complex problems with ease.
To use a tool or library, you need to load it into memory using the require command. For example, you can type the following command in the Console Window:
?- require(xml).
This will load the XML library into memory and display a message like this:
xml.pl compiled 0.01 sec yes
Now you can use the predicates provided by the XML library to manipulate XML documents. For example, you can type:
?- xml_parse('John Smith', X). X = element(book,[title='Prolog for Dummies'],[element(author,[],['John Smith'])]).
This will parse an XML string and return its corresponding Prolog term.
