What does a disposition of (NEW,CATLG,DELETE) mean?

  1. Indicates a new dataset and allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends.

  2. Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step abends.

  3. Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends.

  4. Indicates a new dataset and allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step not abends.


Correct Option: C

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Indicates a new dataset and allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends. This option is incorrect. The correct disposition would be to catalog the dataset if the step is successful, not to allocate and catalog it.

Option B) Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step abends. This option is incorrect. The correct disposition would be to delete the dataset if the step abends, not if it is unsuccessful.

Option C) Indicates a new dataset and needs to be allocated, to CATLG the dataset if the step is successful and to delete the dataset if the step abends. This option is correct. The disposition (NEW,CATLG,DELETE) indicates that the dataset is new and needs to be allocated. If the step is successful, the dataset should be cataloged. If the step abends (fails), the dataset should be deleted.

Option D) Indicates a new dataset and allocated, to CATLG the dataset if the step is unsuccessful and to delete the dataset if the step not abends. This option is incorrect. The correct disposition would be to delete the dataset if the step abends (fails), not if it doesn't abend.

The correct answer is C. This option is correct because it accurately describes the disposition (NEW,CATLG,DELETE) as indicating a new dataset that needs to be allocated. If the step is successful, the dataset should be cataloged, and if the step abends (fails), the dataset should be deleted.

Correct Option: C

How do you reference the most current generation of a GDG (generation data group)?

  1. By placing a +1 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(+1)

  2. By placing a -0 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(-0)

  3. By placing a -1 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(-1)

  4. By placing a +0 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(+0)


Correct Option: D

AI Explanation

To reference the most current generation of a GDG (generation data group), you need to use the syntax DSN=GDG.NAME(+0), which is described in option D.

Let's go through each option to understand why it is correct or incorrect:

Option A) By placing a +1 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(+1) This option is incorrect because by placing +1 in parenthesis, you are referencing the next generation of the GDG, not the current one.

Option B) By placing a -0 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(-0) This option is incorrect because -0 is not a valid syntax for referencing the most current generation of a GDG.

Option C) By placing a -1 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(-1) This option is incorrect because by placing -1 in parenthesis, you are referencing the previous generation of the GDG, not the current one.

Option D) By placing a +0 in parenthesis immediately after a dataset name. As in DSN=GDG.NAME(+0) This option is correct because +0 specifies the most current generation of the GDG.

The correct answer is D. This option is correct because it uses the correct syntax to reference the most current generation of a GDG.

What will make this step run if COND parm is COND=(0,NE)?

  1. Run if return codes from any previous step(s) were equal to zero. Skip this step if the return code from any previous steps are not equal to zero (0,NE).

  2. Run if return codes from any previous step(s) were not equal to zero. Skip this step if the return code from any previous steps are equal to zero (0,NE).

  3. Run if return codes from any previous step(s) were equal to zero. Run this step if the return code from any previous steps are not equal to zero (0,NE).

  4. Run if return codes from any previous step(s) were not equal to zero. Run this step if the return code from any previous steps are not equal to zero (0,NE).
