XREFplus+

The architecture of XREFplus+ is centered around several key components that work together to provide comprehensive JCL documentation management. The main components include the XREFPLUS program, ISPF panels, configuration files, and the z/OS security system. The XREFPLUS program is the core engine that processes JCL source code and generates documentation.

It parses JCL statements, extracts relevant information, and creates a structured representation of the JCL. ISPF panels provide an interactive interface for users and administrators. These panels allow users to view, edit, and maintain JCL documentation.

Configuration files define system parameters, user access, and output formats. These files are used to customize the behavior of XREFplus+ and ensure proper operation within the z/OS environment. The z/OS security system, such as RACF, is integrated to manage user authentication and access control.

The system uses the access control model provided by the z/OS security system. Communication between components occurs through standard z/OS interfaces and utilities. The XREFPLUS program interacts with JCL source datasets and documentation datasets.

The system does not use any external databases or storage mechanisms beyond the z/OS file system. There are no specific network ports or requirements beyond standard z/OS connectivity.
