The COBOL Survival Team for IBM i (AS/400)

People in front of a conputer with code

COBOL developers on IBM i (AS400) – a rare phenomenon?

Even though COBOL on IBM i (AS400) is not nearly as common as the programming language RPG, applications developed in COBOL are no less valuable to your company. But it’s hard to find developers with knowledge of COBOL for IBM i (AS400), and so valuable software assets are often decommissioned simply due to a lack of staff. That’s an expensive and risky undertaking for your company, often with unknown consequences.

Don’t simply throw your valuable COBOL assets overboard!

20% of all new developments on IBM i are COBOL.

About 80% of all card-based transactions worldwide are based on code written in COBOL.

COBOL is an extremely efficient programming language and is a mainstay of the software market.

Even when switching to new applications, you need to understand COBOL code.
