  1. B37

  2. D37

  3. E37

  4. C37


Correct Option: D
Explanation:

To answer this question, the user needs to know about different types of system errors that can occur due to a lack of available disk space.

Each option refers to a specific system error that can occur due to disk space issues, and the user needs to identify the option that is not an example of an abend generated due to a lack of available disk space.

A. B37: This option is an example of an abend generated due to a lack of available disk space. B37 occurs when the system cannot allocate a new data set due to insufficient space.

B. D37: This option is also an example of an abend generated due to a lack of available disk space. D37 occurs when a job runs out of space in a PDS (Partitioned Data Set) or PDSE (Partitioned Data Set Extended).

C. E37: This option is an example of an abend generated due to a lack of available disk space. E37 occurs when a job runs out of space in an SMS-managed data set.

D. C37: This option is not an example of an abend generated due to a lack of available disk space. C37 occurs when a job or program attempts to access a data set that does not exist.

Therefore, the correct answer is:

The Answer is: D. C37

What can be done to eliminate 'NOT CATLG 2' for a particular dataset?

  1. Add a job step to purge the dataset

  2. Run a job to purge the dataset and run it before the job that creates it

  3. Purge the dataset before running the job that creates it

  4. All of the above


Correct Option: D

AI Explanation

To eliminate the 'NOT CATLG 2' error for a particular dataset, you can follow any of the following approaches:

A. Add a job step to purge the dataset: This option is correct because adding a job step to purge the dataset will remove any existing catalog entries for the dataset. This can be done by using appropriate system commands or utilities.

B. Run a job to purge the dataset and run it before the job that creates it: This option is correct because running a job to purge the dataset before the job that creates it ensures that any existing catalog entries are removed before the dataset is created again. This ensures that the 'NOT CATLG 2' error does not occur.

C. Purge the dataset before running the job that creates it: This option is correct because manually purging the dataset before running the job that creates it will remove any existing catalog entries. This ensures that the 'NOT CATLG 2' error does not occur.

Therefore, the correct answer is D) All of the above. All of these options can be used to eliminate the 'NOT CATLG 2' error for a particular dataset.

What is the maximum number of steps in a job?

  1. 251

  2. 255

  3. 254

  4. Any number


Correct Option: B

AI Explanation

To answer this question, we need to understand the concept of "steps" in a job.

In computing, a job refers to a task or a set of instructions that a computer program needs to execute. Each job can be divided into smaller units called steps. These steps represent individual operations or instructions that need to be performed by the computer.

In most computer systems, the number of steps in a job is limited by the size of the step counter. A step counter is a register or variable that keeps track of the current step in a job. It usually has a fixed number of bits, which determines the maximum number of steps that can be represented.

The correct answer is B) 255. This option is correct because the maximum number of steps in a job is determined by the size of the step counter, which is typically 8 bits. With 8 bits, the step counter can represent values from 0 to 255, allowing for a maximum of 256 steps. However, since the step counter starts from 0, the actual maximum number of steps is 255.

  1. response.write("Hello World")

  2. document.write("Hello World")

  3. ("Hello World")

  4. "Hello World"


Correct Option: B
Explanation:

To write "Hello World" in JavaScript, the correct syntax is:

B. document.write("Hello World")

Explanation:

A. response.write("Hello World"): This is not the correct syntax. The "response" object does not have a "write" method in JavaScript.

B. document.write("Hello World"): This is the correct syntax. The "document" object represents the current web page, and the "write" method is used to write content directly to the web page. In this case, it will write "Hello World" to the page.

C. ("Hello World"): This is not the correct syntax. Parentheses alone do not have any specific meaning in JavaScript.

D. "Hello World": This is a string literal and is valid syntax in JavaScript. However, it does not actually write "Hello World" to the web page. It is just a static string value that can be assigned to a variable or used in other operations.

Therefore, the correct answer is B. document.write("Hello World").
