    The step will always be executed within or not a preceding step abnormally terminates when coded as ______           

    • COND=EVEN

    • COND=ODD

    • COND=ONLY

    • None

    Correct Answer
    A. COND=EVEN
    Explanation
    When the step is coded as COND=EVEN, it means that the step will only be executed if the preceding step abnormally terminates and the return code is an even number. In other words, if the preceding step terminates normally or abnormally with an odd return code, the step will not be executed. Therefore, this coding ensures that the step will always be executed within the condition specified.

    In GDG same JCL code can be used to process every cycle with a single  Application .                     

    • True

    • False

    Correct Answer
    A. True
    Explanation
    In GDG (Generation Data Group), the same JCL (Job Control Language) code can be used to process every cycle with a single application. This is because GDG allows for the creation of multiple versions of a dataset, each with a unique generation number. By specifying the GDG base name in the JCL code, the job can automatically process the latest version of the dataset without needing to modify the code for each cycle. Therefore, the statement "True" is correct.

    ___ specifies the largest amount of main memory for any job step within the job.

    • Notify

    • Region

    • Typrun

    • None of the above

    Correct Answer
    A. Region
    Explanation
    The correct answer is "region". In a job, the "region" specifies the largest amount of main memory that can be used by any job step within that job. This setting helps allocate memory resources efficiently and ensures that each job step has enough memory to execute successfully. By setting a maximum region size, the system can prevent a job step from using excessive memory and potentially causing performance issues or system crashes.

  • 20. 

    Concatenation has meaning only for sequential processing

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Concatenation refers to the act of combining two or more strings together. In the context of sequential processing, concatenation is meaningful because it allows for the merging of strings in a specific order. However, in non-sequential processing, where the order of operations is not predetermined, concatenation may not have a clear or meaningful outcome. Therefore, the statement that "concatenation has meaning only for sequential processing" is true.
