Which JCL statement is used to specify the de-allocation of a data set after its use in a job step?

DEALLOC
DELETE
FREE
UNALLOCATE

The DELETE statement is used to specify the de-allocation of a dataset

What are the best practices for handling data set de-allocation in JCL for efficiency and resource management?

De-allocate datasets manually after job completion.
Use DISP=(MOD,DELETE) to modify and de-allocate datasets efficiently.
Use DISP=MOD to modify the dataset, then use DELETE to de-allocate it.
Use DISP=OLD to keep the dataset open until the job completes.

Best practices include using DISP=(MOD,DELETE) to efficiently modify and de-allocate datasets in a single step.

You are responsible for maintaining a set of JCL jobs. How would you troubleshoot issues related to EXIT statements in these jobs, and what are some common debugging techniques?

Debugging EXIT statements involves checking job logs, reviewing system messages, and utilizing the JES2 and JES3 consoles for real-time monitoring.
EXIT statements do not require troubleshooting, as they are processed automatically without errors.
Employ a third-party debugging tool specifically designed for JCL EXIT statements.
Use system logs to identify errors related to EXIT statements and leverage the JES2 and JES3 consoles to monitor the execution of JCL jobs.

Troubleshooting EXIT statements involves checking job logs, system messages, and utilizing JES2 and JES3 consoles for real-time monitoring of JCL job execution.

You have a JCL job with multiple steps. One of the steps requires custom processing based on certain conditions. How would you implement this using an EXIT statement?

Define an EXIT statement within the specific job step, indicating the conditions for custom processing.
The EXIT statement is not applicable for conditional processing in JCL.
Use a global EXIT statement at the end of the JCL job, specifying conditions for the desired step.
Utilize an EXIT statement within the system configuration to apply custom processing to the entire job.

To implement custom processing based on conditions in a specific step, you should define an EXIT statement within that step. This allows conditional execution of code.
