Rational COBOL Runtime for z/VSE

The architecture of Rational COBOL Runtime for z/VSE comprises several key components that work together to enable the execution of COBOL applications generated from EGL. The central component is the runtime environment, which manages the execution of COBOL programs. This environment provides the necessary libraries and interfaces for the programs to interact with the z/VSE operating system and other system resources.

The COBOL compiler interface is another critical component. It handles the translation of EGL code into executable COBOL, ensuring that the generated code is compatible with the runtime environment. System services provide access to various system functions, such as file I/O, database access, and security features.

These services are essential for the COBOL applications to perform their intended tasks. Communication between components occurs through well-defined interfaces and protocols. The runtime environment interacts with the z/VSE operating system using system calls and APIs.

The COBOL compiler interface communicates with the runtime environment to provide the executable code. The runtime environment supports various APIs for integration, though specific methods and protocols depend on the application's design. The product supports authentication and integrates with z/VSE security features.

Compared to other COBOL runtimes, it offers specific support for EGL-generated applications and integration with IBM's development tools. The runtime environment supports standard COBOL syntax and provides interfaces for interacting with system resources. The product facilitates the modernization of COBOL applications by enabling the execution of EGL programs within the z/VSE environment.
