In a JCL job, you need to allocate a dataset with specific attributes, including BLKSIZE and RECFM. How would you accomplish this using the DSN parameter?
- Include the required attributes in the DSN parameter when defining the dataset name.
- Set the dataset attributes in the JOB statement.
- Specify the dataset attributes in the EXEC statement of the job step.
- Use the DD statement with the DSNAME parameter to specify the attributes.
To allocate a dataset with specific attributes in JCL, you would include those attributes directly in the DSN parameter when defining the dataset name. This ensures that the allocated dataset inherits the specified characteristics, such as BLKSIZE and RECFM, meeting the requirements of the job step. Using the DSN parameter in this way simplifies the JCL and makes it more readable.
