Mainframe
COBOL to Java, C#
& Cloud
SoftwareMining modernizes Micro Focus COBOL applications by translating business logic and platform-specific language extensions into maintainable Java or C#. The deterministic translation process preserves the behaviour and processing sequence of the original application while enabling deployment on modern Java or .NET platforms.
Although Micro Focus COBOL is highly compatible with ANSI and IBM COBOL standards, enterprise applications frequently make use of Micro Focus-specific language extensions, compiler directives, runtime libraries, file handling, and database interfaces. SoftwareMining recognises these platform-specific features during analysis and translates them into equivalent Java or C# implementations while preserving the application's functional behaviour.
Many organisations running Micro Focus COBOL applications are seeking to reduce dependency on proprietary runtimes, lower licensing costs, and improve access to modern development tools and skills. While alternative COBOL compilers such as GnuCOBOL may be suitable for some environments, they generally preserve the existing COBOL application architecture. By translating applications into maintainable Java or C#, organisations gain a modern, widely supported technology platform that integrates naturally with today's development, testing, and deployment practices.
Many Micro Focus COBOL systems - especially those adapted from IBM mainframe applications - follow COBOL 85 standards. These programs often use structured coding patterns that create both challenges and opportunities during translation. For such cases, the following resources may be more relevant:
Some Micro Focus applications also use proprietary client-server frameworks that introduce extra features such as advanced screen handling, operating system API wrapping, and Object-Oriented COBOL structures. The next section explores how these features can be refactored efficiently during migration.
Micro Focus COBOL adds a SCREEN SECTION for defining static user interfaces. These are often used in conversational programs designed for client-server environments. SoftwareMining converts these conversational applications into standard application-server architectures.
Many Micro Focus applications also use control characters for screen manipulation, such as clearing or blanking the display.
SoftwareMining replaces these with clear, maintainable methods - for example, translating a control character into a Java blankScreen() function.
Micro Focus COBOL includes many platform-specific API calls. After migration to Java or C#, especially within an application-server environment, most of these calls are no longer needed. Each API reference is analyzed and either replaced or safely removed during translation.
Some Micro Focus COBOL systems were originally migrated from mainframe environments. These require special handling similar to native CICS or DB2 applications. For detailed guidance, see CICS COBOL to Java Conversion and DB2 / SQL COBOL Migration.
