Power JCL

Power JCL is designed with a modular architecture to facilitate JCL validation and standards enforcement on z/OS systems. The core components include the JCL Parser, Validation Engine, JCLScript Interpreter, and Security Interface. These components work together to provide a comprehensive JCL management solution.

1. **JCL Parser**: This component analyzes the JCL syntax, breaking it down into individual statements and parameters. It identifies syntax errors and ensures that the JCL conforms to the basic JCL grammar.

2. **Validation Engine**: The Validation Engine applies a set of predefined rules and standards to the parsed JCL. These rules are defined in configuration files and can be customized to meet specific organizational requirements.

The Validation Engine checks for naming conventions, required parameters, and other site-specific JCL standards. 3. **JCLScript Interpreter**: This component executes custom validation scripts written in JCLScript.

JCLScript allows users to define complex validation rules that go beyond basic syntax checking. These scripts can access JCL parameters, perform comparisons, and issue error messages. 4.

**Security Interface**: The Security Interface integrates with z/OS security systems such as RACF, ACF2, or Top Secret to authenticate users and control access to Power JCL resources. It ensures that only authorized users can modify JCL standards and validation rules. These components communicate through internal APIs and data structures.

The JCL Parser passes the parsed JCL to the Validation Engine, which in turn uses the JCLScript Interpreter to execute custom validation scripts. The Security Interface provides authentication and authorization services to all other components. Power JCL uses configuration files to store JCL standards and validation rules.

These files are read by the Validation Engine during JCL processing. Competing products may lack the flexibility of JCLScript for custom validation rules.
