  2. REFDD=*.stepname.ddname

  3. REFDD=*.jobstepname.procstepname

  4. REFDD=*.jobstepname.ddname


Correct Option: A

AI Explanation

To answer this question, we need to understand the syntax for the REFDD parameter in a job control language (JCL) statement.

The correct syntax for the REFDD parameter is:

A. REFDD=*.ddname

This syntax specifies that the data set referenced by the DD statement with the given ddname should be used as input for the current step or job.

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

Option A) REFDD=*.ddname - This option is correct because it specifies that the data set referenced by the DD statement with the given ddname should be used as input for the current step or job.

Option B) REFDD=*.stepname.ddname - This option is incorrect because it includes the stepname in the REFDD parameter. The REFDD parameter does not require the stepname; it only requires the ddname.

Option C) REFDD=*.jobstepname.procstepname - This option is incorrect because it includes both the jobstepname and the procstepname in the REFDD parameter. The REFDD parameter does not require these names; it only requires the ddname.

Option D) REFDD=*.jobstepname.ddname - This option is incorrect because it includes the jobstepname in the REFDD parameter. The REFDD parameter does not require the jobstepname; it only requires the ddname.

The correct answer is A) REFDD=*.ddname. This option is correct because it specifies that the data set referenced by the DD statement with the given ddname should be used as input for the current step or job.
