“Searching for a tool that analyses our PL/I applications fully automated, completely, quick and reliable, we found Delta and AMELIO. In particular the quality and depth of the analyses and the high level of PL/I competence of Delta have convinced us.”

Many enterprises have developed their business-critical core applications in PL/I. Such systems have grown over years – or even decades – and have been further developed and adapted to new requirements. Naturally, they became larger and more complex and presumably include a lot of dead code. Their present architecture doesn’t comply with the originally intended architecture. Often the original programmers are not available anymore and the maintenance has been carried out by a number of different developers.

To efficiently and securely solve such tasks, it is indispensable to understand the functionality of each application and how the programs interact with each other.

Normally, existing documentations describe how specific calculations are executed but they don’t describe what the application does and what special situations must be considered. The original developers cannot be asked anymore. As a result, the only reliable source of information is the source code itself.

But how can you reliably extract the relevant information from the code?

AMELIO Logic Discovery reliably and efficiently analyses large and complex PL/I applications and helps developers to understand their systems.

AMELIO Logic Discovery for PL/I ...

  • ... derives knowledge about the functionality of the application from the implementation details,
  • ... separates the application logic from the technical infrastructure,
  • ... analyses not only selectively but also considers the relations between the programs,
  • ... works model-oriented and provides the analysis results as language-neutral documentation,
  • ... is configurable and can be perfectly tailored to the requirements of a (modernization) project.

For further details have a look at our Flyer "AMELIO Logic Discovery for PL/I".

LVM VersicherungThe LVM Versicherung (LVM insurance) in Münster, Germany, has developed its business-critical applications in PL/I and was looking for a solution for deep source code analyses to support the further maintenance and modernization.

On the basis of exemplary applications from LVM, we have presented the goals and concepts of AMELIO Logic Discovery. The shown analyses and their presentation have convinced LVM. That is why LVM has now decided to evaluate the functionality and performance of AMELIO Logic Discovery even more detailed as part of a Proof of Concept.
