PLF

PLF enhances JCL for zVSE/VSEn by enabling procedural coding and variable substitution. This allows for more dynamic and reusable batch processing jobs. The architecture of PLF is designed to integrate seamlessly with the existing zVSE/VSEn environment, leveraging its security features and resource management capabilities.

It does not require any major changes to the underlying operating system or system infrastructure. PLF allows you to define variables within your JCL scripts and use them to control various aspects of job execution. This makes it easier to manage complex batch processing workflows.

You can also create reusable JCL procedures that can be called from multiple jobs. This promotes code reuse and reduces redundancy. PLF uses configuration files to define variables, procedures, and other settings.

These files are typically text-based and can be edited with a standard text editor. The system components include the JCL preprocessor, the variable substitution engine, and the procedure execution module. These components work together to transform JCL scripts into executable jobs.

Alternatives include manual JCL coding or other JCL enhancement tools.
