You are tasked with optimizing a JCL job's performance. How can you use the EXEC statement to allocate more resources to a specific step to improve its execution time?
- Include the TCB (Task Control Block) parameter to enhance overall step performance.
- Increase the REGION parameter value in the EXEC statement of the targeted step.
- Set the PRIORITY parameter to 'HIGH' in the EXEC statement of the specific step.
- Use the CPU-TIME parameter to allocate more CPU resources to the desired step.
By increasing the REGION parameter, you allocate more virtual storage, optimizing the step's performance by providing additional resources.
