targetedjcl

TargetedJCL is a Java-based framework designed to simplify the generation and execution of Job Control Language (JCL) for IBM mainframe systems. JCL is a scripting language used to control the execution of batch jobs on IBM z/OS environments, and manually writing JCL can be time-consuming and error-prone. TargetedJCL aims to automate and streamline this process by providing a structured approach to JCL creation through Java code.

The framework allows developers to define JCL jobs programmatically, reducing the need for manual text editing. It supports common JCL operations such as job submission, dataset management, and resource allocation. By encapsulating JCL logic within Java classes, TargetedJCL promotes modularity and reusability, making it easier to maintain and update job definitions.

TargetedJCL is particularly useful in enterprise environments where batch processing is critical. It integrates with existing mainframe workflows and can be extended to include custom logic or third-party tools. The framework also provides validation features to ensure JCL syntax correctness before submission, minimizing runtime errors.

Developed as an open-source project, TargetedJCL is designed to be lightweight and flexible, catering to both developers and administrators managing mainframe workloads. It supports modern Java development practices, including dependency management via Maven or Gradle, and can be deployed as part of a larger CI/CD pipeline for automated job processing.

While primarily focused on JCL automation, TargetedJCL can complement other mainframe tools, such as IBM’s Enterprise COBOL or z/OS Connect, to create cohesive batch processing solutions. Its adoption helps organizations reduce operational overhead while maintaining control over legacy mainframe systems.
