To answer this question, we need to understand the different JCL (Job Control Language) statements and their keyword parameters.
The correct answer is C) PARAM.
Explanation:
The PARAM keyword parameter is used in the PROC statement. It is used to pass values to symbolic parameters defined in the PROC or PARM statements. The PARAM keyword allows you to pass values to these parameters dynamically at run-time.
Let's go through each option to understand why it is correct or incorrect:
Option A) EXEC - The EXEC statement is used to specify an execution control statement or a JCL procedure to be performed. It does not have a PARM keyword parameter.
Option B) DD - The DD (Data Definition) statement is used to define and describe the input, output, and intermediate data sets used by a program. It does not have a PARM keyword parameter.
Option C) PARAM - The PARAM keyword parameter is used in the PROC statement to pass values to symbolic parameters defined in the PROC or PARM statements. This option is correct.
Option D) JOB - The JOB statement is used to identify the beginning of a job and to specify job-level control information. It does not have a PARM keyword parameter.
Therefore, the correct answer is C) PARAM.
