Refal Programming is an artificial programming language designed for symbolic operations, including “word processing, language translation, machine translation, and artificial intelligence.” It’s one of the earliest members of the family of dynamic programming languages, first conceived by David Morrell in 1966. The book covers many aspects of the language including syntax and grammar, basic functions, and the various libraries of standard library and third party libraries.

This book includes a glossary, reference manual, introduction to programming, as well as the Language Reference Manual (also known as the MLA Style Manual) which is used for reference purposes and is included with the text. A glossary of terms is included in the footnotes. An index at the end of each chapter makes it easy to find your way back to the chapter you’re currently reading.

Chapter one is written in the third person. The first paragraph provides an introduction to Refal and includes some background on the language and the authors. It includes a discussion of what makes Refal so unique from other languages. It also includes several examples of how the language is used in practice.

The language is very similar to the ML programming language. It has many features, such as:

The language takes a functional approach to programming and makes it very easy to read and write programs. In particular, there are no built in types; instead, programmers have to use the typedef facility. This facility gives programmers the ability to define and use any type they want for any program. This allows them to be more flexible in the design of their programs and avoid bugs that arise from using too many types for the same function.

One of the benefits of the Refal programming language is that it is not dependent on any external tools or libraries for support. Instead, programmers have to use their own libraries and tools to implement all aspects of the language. The language is an interpreted programming language, which means that it works best when programmers can see their code working rather than just reading it.

Some of the chapters focus on specific features of the language and cover some basics of how it works and uses. The chapters include:

This book is well organized and contains many examples of how the language can be used. It covers all the basics, but doesn’t get into details that might make the language too complicated. complex to understand.

In the later chapters, the author gets a little more advanced and starts using a few advanced features. For example, she goes over recursion and data structures in detail. But she spends only about a page on recursion and barely mentions data structures in any of the chapters.

These chapters do contain a couple of exceptions. For example, in chapter three, she introduces a special case of null pointer error that occurs when programmers try to dereference an object that is not null. Unfortunately, it is not covered in the rest of the text.

The final chapter deals with a very common problem that arises in programs: the problem of trying to dereference a null pointer. using null values. There are many ways that this could happen, including when an object is left out of scope, an invalid reference, a variable being set to a null value, an undeclared variable, and invalid indexing.

The author provides some simple rules that she uses to avoid these problems, but they are not clearly explained. The chapter ends with a review of what you can do if this happens.

However, it does go into more depth on the language and some of its problems and pitfalls. The book is well organized and well written, but it would benefit to be updated and with a few more examples of how to use the language. Overall, it is a good introduction to the language.
