Show answer
Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of condition codes in job control language (JCL).

In JCL, a condition code is a numeric value that represents the success or failure of a jobstep. A return code of 0 typically indicates successful execution, while a non-zero return code indicates an error or failure.

To specify a condition for a jobstep to be executed based on the return code of the previous jobstep, you need to use the COND parameter in JCL.

In this case, you want the jobstep to be executed only if the previous jobstep has a return code of strictly less than 8. To achieve this, you need to use the COND parameter with the condition code (8,LE), where LE stands for less than or equal to.

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

Option A) COND=(8,LE) - This option is correct because it specifies that the jobstep should be executed if the return code of the previous jobstep is less than or equal to 8. This satisfies the condition of strictly less than 8.

Option B) COND=(8,GE) - This option is incorrect because it specifies that the jobstep should be executed if the return code of the previous jobstep is greater than or equal to 8. This does not satisfy the condition of strictly less than 8.

Option C) COND=(8,LT) - This option is incorrect because it specifies that the jobstep should be executed if the return code of the previous jobstep is less than 8. This does not satisfy the condition of strictly less than 8.

Option D) COND=(8,GT) - This option is incorrect because it specifies that the jobstep should be executed if the return code of the previous jobstep is greater than 8. This does not satisfy the condition of strictly less than 8.

The correct answer is Option A) COND=(8,LE). This option is correct because it specifies the desired condition of strictly less than 8 for the jobstep to be executed.

Consider the following: //TU00001T JOB ATUT000,TU00001,CLASS=7,MSGCLASS=X,TIME=(,10) //STEP1 EXEC PGM=PROGRAM1,TIME=(,6) //STEP2 EXEC PGM=PROGRAM2 //STEP3 EXEC PGM=PROGRAM3,TIME=(,15) Which of the following statements are true ?

What are the correct values for the DSN parameter of a temporary data set?

technology mainframe

  1. &NAME&(TEMP)

  2. &&TEMP(NAME)

  3. &&NAME

  4. &NAME

Show answer
Correct Option: B,C

AI Explanation

To answer this question, we need to understand the format and usage of the DSN parameter for a temporary data set.

The DSN parameter is used to specify the name and characteristics of a data set in a JCL (Job Control Language) statement. Temporary data sets are typically used for temporary storage during the execution of a job and are deleted automatically after the job completes.

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

Option A) &NAME&(TEMP) - This option is incorrect because it does not follow the correct format for a temporary data set. The correct format for specifying a temporary data set is &&TEMP(NAME), where TEMP is the generic name and NAME is the specific name.

Option B) &&TEMP(NAME) - This option is correct because it follows the correct format for a temporary data set. The double ampersand (&&) indicates that it is a temporary data set, TEMP is the generic name, and NAME is the specific name.

Option C) &&NAME - This option is correct because it follows the correct format for a temporary data set. The double ampersand (&&) indicates that it is a temporary data set, and NAME is the specific name.

Option D) &NAME - This option is incorrect because it does not follow the correct format for a temporary data set. The double ampersand (&&) is missing, which indicates that it is not a temporary data set.

The correct answer is Option B and Option C. These options are correct because they follow the correct format for specifying a temporary data set in the DSN parameter.
