CodeTurn

Astadia

CodeTurn is Astadia’s automated mainframe code conversion product, built to automatically transform legacy source code into modern source code that is maintainable and 100% functionally equivalent to the original. It takes an application’s source code and converts it to functionally identical sources, ready to run in an alternative environment on the same platform or on a different platform altogether. Because the conversion and testing are fully automated, the outcome of the modernization project becomes highly predictable in terms of risks, costs, and duration. The migrated application is free of dependencies on proprietary Astadia software and relies on native industry-standard technologies instead. CodeTurn integrates all aspects of conversion to produce high-quality, functionally equivalent code and is typically used with Astadia tools such as DataTurn for legacy data migration, TestMatch for automated testing, and DataMatch for automated batch testing.
