Rocket PRO/JCL

The architecture of Rocket PRO/JCL is designed for robust JCL validation and integration within the z/OS environment. The main components include the JCL Parser, Rule Engine (REXX-based), Dataset Validator, and Security Interface. The JCL Parser is responsible for analyzing JCL statements, identifying syntax errors, and extracting relevant information.

The Rule Engine, powered by REXX, allows for the definition and enforcement of JCL standards. The Dataset Validator checks for dataset existence, attributes, and access permissions. The Security Interface integrates with z/OS security systems, such as RACF, to validate dataset access and prevent unauthorized actions.

Communication between components is primarily internal, with the CLI serving as the primary external interface. Configuration is managed through configuration files, which specify parameters for JCL validation, dataset validation, and security checks. The tool does not use a dedicated database; it relies on z/OS system resources and security configurations.

Network requirements are minimal, as PRO/JCL runs on z/OS and interacts with local resources. The CLI provides commands for validation, rule management, and reporting. For example, the `PROJCL VALIDATE` command initiates the JCL validation process, while `PROJCL LISTRULES` displays the active rules.

The logging system records validation results, errors, and other relevant information, which can be used for monitoring and troubleshooting. The tool's design emphasizes efficiency and integration with the z/OS environment, providing a reliable solution for JCL validation.
