PEngiCCL

The PEngiCCL architecture comprises several key components. The macro processor is responsible for expanding PEngiCCL macros into standard COBOL code. This process occurs during the compilation phase.

The COBOL compiler then processes the expanded code, generating executable modules. The z/OS operating system provides the runtime environment and manages system resources. Communication between these components is managed through the z/OS system.

Configuration files, specific to the applications using PEngiCCL, store settings and parameters. These files are read during the application's initialization phase. Security is handled by the z/OS security infrastructure, such as RACF, which manages user authentication and authorization.

Audit and logging capabilities are provided by the z/OS operating system and the applications built using PEngiCCL. PEngiCCL does not expose APIs in the traditional sense. Instead, it provides a macro language that integrates directly with COBOL.

This approach differs from modern development environments that use REST or SOAP APIs. The use of PEngiCCL promotes code reuse and simplifies complex COBOL tasks, which can lead to significant improvements in development efficiency and maintainability. The primary storage mechanism is the z/OS file system, which stores the COBOL source code, configuration files, and compiled modules.

Network requirements are minimal, as PEngiCCL operates within the mainframe environment.
