Dos and Don’ts of Becoming a Highly Effective COBOL Application Developer

As a programming language that has stood the test of time, COBOL (Common Business Oriented Language) continues to be a crucial skill for application developers working in finance, business processing, and government systems. Even though it might seem archaic compared to modern programming languages, COBOL remains vital for maintaining and upgrading existing systems.

The Dos

Do Master the Basics Thoroughly

Understanding the core principles of COBOL is imperative for any developer looking to make a mark in this field. Master procedural programming, control flow, data division, and file handling, as these form the backbone of any COBOL application.

Do Keep Up with Modern Developments

COBOL has evolved over the decades, and modern iterations incorporate object-oriented elements and updated data structures. Stay abreast of these developments to remain relevant and effective in your role.

Do Emphasize Clean Code Practices

Writing clean, well-documented code is essential not only for current readability but also for future maintenance. Emphasize clarity and simplicity in your coding practices to prevent issues later.

Do Collaborate and Communicate

Effective communication within your team can lead to more efficient and successful projects. Regular collaboration with other developers and stakeholders ensures that all aspects of a project are aligned and personally understood.

Do Test Extensively

Rigorous testing is crucial in COBOL development. Given the critical nature of many COBOL applications, ensure that you have comprehensive testing procedures in place before any deployment phase. Thorough testing helps to identify and remediate errors early.

Do Engage in Continuous Learning

The world of technology is constantly evolving. Engage in continuous learning by attending workshops, enrolling in online courses, or participating in forums to keep your skills sharp and updated.

The Don’ts

Don’t Neglect Documentation

Documentation is often overlooked, but it is fundamental to ensuring that applications are maintainable and understandable by future developers. Never underestimate the importance of thoroughly documenting your code and development processes.

Don’t Ignore Legacy Systems

Many organizations rely on legacy systems that have been running for decades. Don’t dismiss these systems as outdated. They often contain intricate logic and high-value data. Understanding and optimizing these systems is a crucial skill.

Don’t Overcomplicate Your Solutions

While it might be tempting to utilize complex logic and solutions, simplicity is key. Over-complicating an approach can lead to errors and increased maintenance overhead. Aim for solutions that are as straightforward and efficient as possible.

Don’t Resist New Tools and Techniques

System enhancement tools and modern development environments can greatly improve the efficiency and effectiveness of COBOL programming. Be open to adopting new technologies and techniques that can streamline your development process.

Don’t Work in Isolation

COBOL development often involves various interconnected systems and applications. Working in isolation can lead to integration issues and misaligned project outcomes. Collaborate and seek feedback regularly to ensure cohesive development strategies.

Don’t Underestimate Security

Given the sensitive nature of many COBOL applications, security should always be top of mind. Don’t underestimate the importance of incorporating security practices into every aspect of your development cycle.

Conclusion

Becoming a highly effective COBOL application developer requires a combination of foundational knowledge, continuous learning, and strategic collaboration. By following the dos and avoiding the don’ts outlined, you will not only enhance your skills in COBOL but also add significant value to your team and organization.
