Best Cobol Books to Learn

6 minutes read

COBOL is an abbreviation representing Common Business Oriented Language. Both procedural and object-oriented in nature. In computing, compilers convert computer languages published in elevated linguistics into assembly language that the computer is capable of understanding. It takes a file or set of facts and processes it before displaying the results. It is a programming language that receives input, does calculations, and then produces the results.


The computer Language, which has been around for more than six decades, got its current moniker on September 18th, 1959. Developed by the United States Defense section in the late 1950s. This is a standard mainframe commerce language.


What is COBOL used for?


The applications, designed for transaction processing, assist with a wide range of tasks, including managing payrolls, state pension funds, hotel bookings, and other entities. According to most estimates, over three trillion dollars in daily transactions are supported by this programming system.


COBOL is a specialized or domain-specific language. Programming for business is the focus here. Keeping the it’s tale alive results in its specificity, portability, and understandable syntax.

Why is COBOL still used today?


Many equally good arguments explain why this language is still in use today. One of the advantages of the language is that it is very versatile and stable. For example, banks want 100 percent precision in their transactions. In this regard, COBOL trumps Java. Another issue is that many of the world's largest corporations rely on core programs based on this language, and intervention is either too hazardous or costly. As the digital world evolves, it’s ability to bring both creativity and stability is becoming more important in the IT industry.


The top COBOL compiler suppliers include Micro Focus, IBM and Fujitsu. While a scarcity of competent programmers of this language is generally acknowledged as a problem, alternatives are available.


Visual Studio and Micro Focus are compatible with Visual PE. Development of this computer language in both Eclipse and Visual is simplified. This capability of transferring essential goods and services from their current platforms to new ones that will allow for future innovation is included in many digital transformation programs.


Is COBOL difficult to learn?


This is not a foreign language that must be learned from scratch as it is English. It is composed of structural components similar to English, including verbs, phrases, and sentences. Its readability enables you to comprehend what software would do without having to master a new syntax.


Every hardware platform can run this language now. This "write once, run everywhere" language helps organizations reuse it’s systems built decades ago on modern platforms like .NET or JVM, allowing them to save money and resources. The language's data types and hierarchies allow developers to design programs that can be easily transferred to other platforms. The use of this language on every new corporate platform since its inception shows it’s adaptability.

Unexpectedly, there aren't many complete video courses available on prominent learning networks for COBOL. Coursera and Udemy provide a few classes. However, most of them are either of bad quality or too sophisticated for the ordinary newcomer to the language.


To help you improve your COBOL abilities, various free, open-source resources are available. The Open Mainframe Project has compiled a list of courses and other information. Information about anything mainframe is found in this area. Groups offers a free course on GitHub that covers all the fundamentals of programming:


Is COBOL faster than C?


Due to the dynamic nature of every binding in Micro Focus OO COBOL, the initial version of it will operate much slower this standard computer language. Because Smalltalk settings have been constantly tuned for more than 20 years, the campaign initiated by OO COBOL compilers will most likely not create code as efficient as Smalltalk. As with C++, ANSI OO COBOL will enable static and dynamic binding.


Sometimes. It varies depending on the work in question. If you ask if a screwdriver or a hammer is quicker, you ask a hypothetical question. Neither is inherently better than the other, yet depending on the work at hand, one may favor one over the other.


These are written down to machine code; they are almost identical when stripped down to their raw metal equivalents: a hammer and a screwdriver are composed of wood and steel, respectively.


To do various sorts of activities, the language has been optimized. Code written in C that is competitive with Cobol is undoubtedly possible; however, you might have to create a lot of hoops and fine-tune the code.


The good news is that you can do a wide range of jobs in C that would be impossible in this language. A-C compiler is most likely used to write the Cobol Compiler. Is it true that every Cobol program is also a C program, and if so, what does it mean?
