Show answer
Correct Option: A
Explanation:

To solve this question, the user needs to have knowledge of Job Control Language (JCL).

The maximum length of a single line of JCL is an important consideration while writing mainframe JCL. JCL statement can be continued onto the next line by inserting a hyphen (-) in column 72 of the JCL statement. This is referred to as JCL continuation.

Now, let's go through each option and explain why it is right or wrong:

A. 71 bytes: This option is correct. The maximum length of a single line of JCL is 71 bytes. Any JCL statement that exceeds this limit should include a continuation character (-) in column 72.

B. 60 bytes: This option is incorrect. The maximum length of a single line of JCL is greater than 60 bytes.

C. 55 bytes: This option is incorrect. The maximum length of a single line of JCL is greater than 55 bytes.

D. 80 bytes: This option is incorrect. Although 80 bytes is a common length for lines of code in other programming languages, it is not the maximum length of a single line of JCL.

The Answer is: A. 71 bytes
