Programming Systems

Highest quality programming systems form the foundation for the efficient running of advanced business-critical applications on BS2000 systems

Applications for BS2000 or their component parts are implemented using both modern and classical programming languages. Java is particularly popular for web-based applications. Traditional languages, such as COBOL or C/C++, tend to be used more when expanding upon existing applications.

The state-of-the-art development environment
Fujitsu provides powerful, all-inclusive tools for programming BS2000 applications. The development workstation is generally a Windows platform. Products available on the international market are integrated into this environment, providing support through all stages of the implementation phase and work hand-in-hand with BS2000 systems.

All this is aimed at optimizing the execution of applications in BS2000 and integrating them into the overall system environment, e.g. by linking them to the transaction monitor or databases.


Powerful debugging system for increasing productivity in the software development and maintenance phase.


Assembler for creating programs in machine code for the /390 architecture.


A powerful high-level programming language supporting the principles of object-oriented programming


Most commonly used programming language to solve tasks for commercial applications with a mature modern COBOL compiler that also supports object-oriented programming.


Programming language for commercial data processing solutions.


Supports program design and generative program building based on structured programming principles.


Common run-time environment required for running source programs compiled with the C/C++, COBOL2000 and COBOL85 compilers


Powerful development system used for FORTRAN-based productiv applications

JENV (BS2000)

The Java™-based development and runtime environment for portable and secure Web applications.


BS2000 variant from the Pascal-XT compiler family, enabling program sources code to be compiled on all supported systems.


Optimizing compiler suitable for commercial as well as technical/scientific applications.
