  • Limited
  • More
  • No
  • Similar
The use of user-defined abend codes provides more flexibility in job control.

In JCL, what does LRECL represent for a dataset, and how is it defined?

  • Logical Record Length, file attributes
  • Logical Record Length, file ownership
  • Logical Record Length, job parameters
  • Logical Record Length, specifies length
LRECL stands for "Logical Record Length," defining the length of each record in the dataset.

When using the IF statement in JCL, you can specify both _______ and _______ conditions.

  • Logical
  • Multiple
  • Sequential
  • Single
The IF statement in JCL allows specifying both multiple and logical conditions

In JCL, what is the function of the PEND statement?

  • Marks the end of a dataset
  • Marks the end of a job
  • Marks the end of a job step
  • Marks the end of a procedure
The PEND statement marks the end of a job step

Which part of a JCL job does the PEND statement mark the end of?

  • Marks the end of a job
  • Marks the end of a job card
  • Marks the end of a job step
  • Marks the end of a procedure
The PEND statement marks the end of the entire JCL job (job stream)

What is the difference between SORT and MERGE operations in the JCL SORT utility?

  • MERGE is used for merging sorted files
  • MERGE is used for removing duplicates during sorting
  • SORT is used for arranging data in ascending order
  • SORT is used for sorting numerical data
SORT is for sorting, while MERGE is specifically for merging sorted files and not for sorting individual datasets

The REGION parameter specifies the _______ that is allocated for the job step.

  • Memory
  • Size
  • Space
  • Storage
The REGION parameter in JCL specifies the storage allocated

To keep a data set available for read-only access but prevent further updates, you can use DISP=_______.

  • MOD
  • NEW
  • OLD
  • SHR
DISP=SHR keeps a data set available for read-only access.

Can you specify different dispositions for different conditions when de-allocating data sets in JCL?

  • No, disposition is a global parameter
  • No, disposition is uniform for all datasets
  • Yes, but only for specific dataset types
  • Yes, using conditional processing in JCL
Different dispositions can be specified for different conditions in JCL

Can the LRECL attribute be larger than the actual record length of a dataset in JCL? Why or why not?

  • No, it causes data corruption.
  • No, it must match the actual record length.
  • Yes, for better performance.
  • Yes, to accommodate future expansion.
LRECL should match the actual record length to avoid data issues.
