The CodeTurn Assembler Migration provides an automatic conversion of legacy Assembler to functionally equivalent C# or Java programs that run on Open Systems. The generated C#/Java code is of an unprecedented quality in the field of Assembler migration, and enables the migration of applications that were previously considered to be unfit for migration.
For the longest time, legacy applications with a substantial portion of business logic written in Assembler (IBM z/OS, z/VSE or BS2000/OSD) were sentenced to eternal life on the legacy platform. The main points preventing their migration to Open Systems:
With the development of the CodeTurn Assembler Migration tools finally a viable option is provided for this type of applications.
Currently the following technologies are supported:
Usually, CodeTurn operates on the application source code, as that is where the real business logic can be found. For the Assembler Migration this is slightly different as this starts exclusively from the expanded Assembler compilation listings – as can be generated with the assembler on the mainframe. This chosen approach avoids the need to emulate both the Assembler Directive and Macro (directive) behavior at runtime on the target platform, and allows an elegant conversion of the Assembler source code.
Any negative impact the expansion of the User Macro’s might have on the readability of the migrated source code, is mitigated by the migration tool e.g. by the preservation of the Assembler DSECT names.
The migration solution covers each of the following elements of a mainframe Assembler applications:
Every mainframe assembly program is converted to a corresponding C# program or Java program.
The generated C#/Java code can be parametrized on multiple levels to optimally blend in with customer standards in these technologies:
The original application comments (both the Full Line and Inline comments) are preserved in the target source code to enable future application maintenance.
Typically, the Assembler logic is only one part of the complete customer legacy code. For the most commonly used mainframe technologies (COBOL, Natural, IDMS, …) Anubex has developed migration solutions to C#/Java as well, and the migrated Assembler code seamlessly integrates with them.
Although the preferred approach is to work with the fully automatically converted code, in some particular cases a manual rewrite of a particular piece of Assembler code can be preferred. Such selective, limited scope rewrites can be performed and easily integrated in the automatically converted code as well.
