Cobol vs Fortran Ultimate Comparison

COBOL and FORTRAN, both are pretty old programming languages, known for their use-cases.

Cobol stands for Common Business-Oriented Language, whereas FORTRAN stands for Formula Translation.

In this article, we will explore the core difference between Cobol and FORTRAN.

Cobol vs Fortran

But, before, we do so, let’s quickly take a look at their origin history.

FORTRAN was created by John Backus at IBM. He did it in 1957. It was mainly aimed at computers and hence known as a computer language. This made a need for a language that needs to be business-oriented. And, that’s why in the ’50s came a business computer Oriented programming language that can be used to read addresses and names. It is known as COBOL, which has the ability to manipulate records as well.

Cobol, unlike FORTRAN, was FLOW-MATIC, which made it not so impressive on the technical side. In fact, computer scientist does not like it and termed it as one of the worst computer languages out there.

In fact, both languages are entirely different based on structure and functionality. FORTRAN was literally designed for scientists‘ help, on the other hand, COBOL plays in the ground of auditors. But both languages are high-level languages. COBOL is a structured and formalized language, but FORTRAN is in free form.

Let’s check out their difference in a tabular format.

Cobol vs Fortran Key Features

COBOL

FORTRAN

Purpose COBOL was developed for business applications. It has been used in Banking Systems, Insurance Companies, and government departments.

 

FORTRAN was developed for formula Translation in mainframe computers, specifically, it is suited for scientific and mathematical complex calculations.

 

Objects Since 2002, it has been revised and adds functions that make it an Object-Oriented language.COBOL Object-Oriented Programming extension is called “ADD 1 TO COBOL GIVING COBOL”. Since 2003, FORTRAN has been an Object-Oriented Language. If you intend to obtain class-like behavior, a module containing the specific methods should be combined. The methods operate on the class, with a derived type that contains the data.
Imperative COBOL is an imperative Programming language; it tells the program “How to do”. The impressive feature about COBOL is designed in an imperative and procedural way.

 

FORTRAN is a compiled imperative language as well as an Object-oriented language.
Functional Yes, Cobol is a functional language. Cobol is not created as an exactly functional programming language. Modern Fortran programming lets the programmer use functions to express code mathematically by minimizing bug-prone mutable states and to encourage good functional discipline. As FORTRAN is a functional language too, the computations can be completed with state changes and mutable data.

 

 Procedural Cobol is a procedural language. As with other procedural languages, it is written in a sequence of commands that tells the computer “What to do”.COBOL does not support procedural recursion. FORTRAN is a compiled imperative programming language that is best suited for scientific computing and numeric computation.
 Generic Language Cobol is not a generic language. However, support for generic language can be made available with the help of parameterized classes. FORTRAN is a generic language which means it is efficient as compile-time mistakes can be solved faster.
 Effectiveness Cobol is a highly reflective programming language; it can modify its structure and behavior. FORTRAN is also very effective when it comes to doing computations.
 Event-driven Cobol is no need to include event-driven. It can simplify programming for event-driven environments and save the procedural structures of any program.  FORTRAN is also not event-driven.
Other Paradigms Procedural, Imperative, and object-oriented. Concurrent, array-based, shared-memory/native distributed parallelism and vectorized.
 Revision It has been revised four times from its standardized date 1968.  It was revised nine times.
 Typing COBOL has a Weak and Static typing discipline. FORTRAN has strong, static, and manifests-based typing discipline.
 Developed by COBOL is developed by CODASYL, ANSI, ISO

Cobol vs Fortran: Uses Cases and Significance

The above tabular format gives a good idea of the technical difference between COBOL and FORTRAN. However, there is much more to their comparison.

Programming languages are tools just like how carpenters use their toolbox to create furniture or beautiful crafts.

From the name itself, we can get a good understanding of what each one of them has to offer.

FORTRAN stands for FORmula TRANslation. This clearly means that it is aimed at engineering or scientific purposes. COBOL, on the other hand, stands for Common Business-Oriented Language and is meant to be used for business-related tasks such as data processing.

So, what happens if someone wants a programming language that fits in both domains?

Well, IBM tried to solve this by creating ALGOL, but it became a hot mess and lost its importance in the programming industry.

Another interesting difference between the two is that COBOL utilizes 8 characters whereas Fortran uses 6-bit characters. This leads to an interesting approach when it comes to handling data that cannot be handled within the 8-bit character limit. The CDC data which had 60-bit words cannot handle the limitation. The workaround is to waste the 54 bits or find another way to pack them in the ratio of 10:1 words.

Is COBOL or FORTRAN in use Today?

Another interesting way to learn about their difference is to see how they are doing right now.

So, if you look at COBOL, you will find that it is still in use while also being one of the oldest programming languages. There are 220 billion lines of code that are currently in the production state.

The Banks and Federal systems mainly use COBOL for their banking systems and ATM. So, the next time you do ATM Swipe, you are indirectly using a system that uses COBOL. In numbers, 95$ of the ATM swipes uses the COBOL code. When it comes to banking systems, 43% utilize the COBOL code. The other industry that uses COBOL includes transportation systems and insurance companies.

If you are a COBOL expert, you are bound to get $10K more salary compared to a developer who doesn’t.

COBOL will continue its growth in the near future. However, many businesses are already looking to replace their old code base with new ones. The modernization might take some time, but until then there would be COBOL used in the systems.

FORTRAN, on the other hand, doesn’t enjoy the same level of success as that of COBOL. But, that doesn’t mean nobody uses it. Physicists utilize FORTRON to their advantage as it helps them do high-performance computing calculations.

Conclusion

The fact that both COBOL and FORTRAN are created for a completely different purpose makes them quite indistinguishable. However, according to a computer scientist, COBOL is not a great programming language. It lacks strong typing, doesn’t support event-driven, and lacks generic language procedures.

FORTRAN, on the other hand, seems to offer an excellent programming language for the time it was released. It also manages to show popularity now because of its usefulness in scientific endeavors.
