Old Programming Languages: Are They Still Relevant?

By Truelogic Software

In the early days of computing, there were only a handful of programming languages that were used to create software. These languages were very primitive, and they were often difficult to use. However, they laid the foundation for the modern programming languages we use today.

As computing technology has evolved, so too have programming languages. New languages have been created that offer more features and capabilities, and they have become easier to use. However, some of the older languages are still in use today, and they continue to be relevant for various reasons.

Legacy Languages in Modern Development 

The relevance of older programming languages is due to the sheer number of legacy systems still in use. These systems were built using older languages, which can be very expensive and time-consuming to rewrite in a newer language. As a result, many organizations continue to maintain and update their legacy software using the original programming languages.

For example, the COBOL programming language was developed in the 1960s and is still widely used in the financial industry. This is because many systems used to process financial transactions were written in COBOL, and it would be costly and time-consuming to rewrite them in a newer language.

Old programming languages are often used in specialized domains. For example, the FORTRAN programming language is still widely used in scientific computing, and the Ada programming language is still used in safety-critical applications.

With the speed of development and the constant innovation in programming languages, many companies may choose to stick with what they know, that is, until there becomes a need to implement a new coding language. 

Advantages Of Newer Alternatives

In some cases, old programming languages can have advantages over newer alternatives. For instance, some old languages are known for their efficiency and performance, which can be important for certain applications.

Just because there are newer coding options that does mean that developers abandon the programming languages they already know. There are still relatively large and active communities of developers that can provide support and resources.

For example, the C programming language is known for its efficiency and performance. This is why it is still widely used for system programming, embedded systems, and game development.

The FORTRAN programming language also has a large and active community of developers, and this is why it's still widely used in scientific computing.

With access to support and expertise, companies don't have to go through the painstaking process of updating or migrating their systems when it may not be necessary or beneficial to them. This saves time and money in the development and maintenance process.

Modernization Efforts 

There are a number of ongoing efforts to modernize and adapt old programming languages to contemporary development needs. These efforts include developing new features and capabilities for old languages, as well as creating tools that make it easier to integrate old and new code.

For example, the Ada programming language has been updated with new features and capabilities, such as support for object-oriented programming. There are also a number of tools that make it easier to integrate Ada code with code written in other languages.

Though integrations can be performed, it's not met without its challenges. Some of them include: 

  • Different programming paradigms make it difficult to integrate code written in other languages.
  • Different APIs create difficulties in calling functions or methods in code written in different languages.
  • Different data types make it difficult to pass data between code written in different languages.
  • Different compilers and interpreters make it difficult to compile or run code written in different languages.


And even though bridging the gap is not always straightforward, many dev communities are banning together to keep the old programming languages alive. A few are: 

The Retrocomputing community is a group of enthusiasts who are interested in preserving and using old computers and software. This community provides a forum for sharing information and resources and for helping people learn about and use old programming languages.

The LLVM project is a compiler infrastructure that supports a wide variety of programming languages, including old languages such as Cobol and Fortran. LLVM provides several tools that can be used to convert code from one language to another and to improve the performance of code written in old languages.

The Rosetta Code project is a collection of programming problems that have been solved in a variety of languages. This project can be used to learn about different programming languages and to see how the same problem can be solved in different ways.

These are just a few of the many community initiatives aimed at bridging the gap between the old and new. These initiatives help people learn about and use old programming languages and transition to newer languages.

Knowledge in Old Programming Languages Still in Demand

The demand for developers skilled in old programming languages is still strong. This is because many legacy systems need to be maintained and updated, and there are not enough developers with the skills to do this work. As a result, there are many job opportunities for developers who know old programming languages.

  • Legacy system analyst: Analyzes and understands legacy systems, identifying areas for improvement and recommending solutions.
  • Legacy system programmer: Maintains and updates legacy systems, including fixing bugs, adding new features, and migrating the systems to new platforms.
  • Legacy system architect: Designs and implements solutions for modernizing legacy systems.
  • Legacy system consultant: Provides advice and guidance on maintaining and modernizing legacy systems.
  • Legacy system trainer: Trains employees on how to use legacy systems.

The Bureau of Labor Statistics projects that the demand for software developers will grow by 26% from 2021 to 2031, much faster than the average for all occupations. This growth is driven by the increasing demand for software applications in various industries across a global market

Factors Influencing Relevance

The relevance of old programming languages is influenced by a number of factors, including the following:

  • The age and complexity of the legacy systems that are still in use.
  • The availability of developers with the skills to maintain and update these systems.
  • The efficiency and performance of the old languages.
  • The features and capabilities of the old languages.
  • The availability of tools and resources for modernizing old languages.

The relevance of old programming languages will likely decline over time as newer languages become more powerful and versatile. However, they will likely continue to be used for some time to come due to the factors mentioned above.

Balancing Old and New 

Using older programming languages can be useful in fields with well-established norms and practices. This is because a range of applications in these sectors have been created using these languages, which have been available for a while. 

Because of this, there is a sizable pool of skilled programmers well versed in these languages, and numerous libraries and tools may be utilized to create applications in these fields.

It's important to note that old programming languages may not be the best choice for all situations. Newer languages often have features that make them more expressive and easier to use. As a result, they may be a better choice for developing applications that require a high degree of flexibility or need to be developed quickly.
