technology mainframe

  1. Linkage Variables

  2. Parameters

  3. Control Libraries

  4. Includes

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of JCL (Job Control Language) statements. JCL is a scripting language used on IBM mainframe operating systems to control batch processing.

The fields in JCL statements that contain specific values designed to direct and control the execution of the statement are called "Parameters."

Option A) Linkage Variables - This option is incorrect because linkage variables are used in programming languages like COBOL to pass data between different programs or modules. They are not specific to JCL statements.

Option B) Parameters - This option is correct because parameters are the fields in JCL statements that contain specific values to direct and control the execution of the statement.

Option C) Control Libraries - This option is incorrect because control libraries are used in JCL statements to specify the location of system control programs or procedures. They are not the fields that direct and control the execution of the statement.

Option D) Includes - This option is incorrect because includes are used in JCL statements to include external files or libraries into the JCL. They are not the fields that direct and control the execution of the statement.

The correct answer is B) Parameters. This option is correct because parameters are the fields in JCL statements that contain specific values to direct and control the execution of the statement.
