PL/I Modernisation

PL/I has been used in legacy business applications by many organisations since the 1960s. However, due to high maintenance costs, and a rapidly shrinking pool of skilled PL/I developers, many organisations are looking for modern alternatives. Our automated PL/I conversion service delivers pure COBOL, Java or C#, and guarantees functional equivalence as compared to the legacy environment, whilst leveraging the advantages of modern platforms and development practices.

Understanding key issues


Expensive resources

Whilst there are significant costs associated with talent acquisition, the impact on internal resources can also be costly, with an average of 75 per cent of development resources spent on maintaining applications.

Feature freeze

Many mission-critical applications are on legacy systems without a roadmap for significant feature improvement. PL/I’s development roadmap doesn’t reflect the value of the data stored within it.

Struggling to stay current

In recent years, modern agile practices such as continuous integration and DevOps, have intensified the troubles associated with sluggish development cycles in legacy environments.

Difficulties with integration

If new applications are developed using modern technologies, integrating these with core business functionality running on legacy systems is a time intensive and risky task.
