Dyalog DNA

We are the creators of Dyalog APL, a powerful array-oriented programming language designed for concise, expressive problem solving. Our team is dedicated to its ongoing development and long-term maintenance, ensuring it continues to meet the evolving needs of our users.

To support this, we provide a suite of development tools and environments that enable both Subject Matter Experts and IT professionals to rapidly turn complex ideas into robust, efficient software solutions.

We are proud of our traditions and how we got here, and honour that by striving to:

  • empower our users to design and build their own software tools with Dyalog.
  • keep Dyalog up-to-date with advances in modern demands and technologies.
  • provide no-nonsense interfaces that enable Dyalog to be fully integrated in the development and production environments.
  • promote use of the APL language, and encourage anyone who has an interest to develop their knowledge.
