How can a comment be added to a MOV_ step instruction?

In programming and scripting languages, comments are used to annotate the code, providing explanations or notes for future reference without affecting the execution of the code. In many programming contexts, placing a double slash "//" before a comment is the standard way to denote that everything following the slashes on that line is a comment. This approach is widely adopted in languages like C++, Java, and JavaScript, making it easily recognizable for those familiar with these conventions.

In the context of adding a comment to a MOV_ step instruction specifically, using double slashes ensures that the code interprets everything that follows only as a note for human readers and not as an executable command. This practice enhances clarity in the code and helps maintainability, as it allows engineers or operators to provide context regarding specific actions within the MOV_ instruction.

Other methods mentioned do not typically serve as standard comment indicators in most programming languages. Parentheses, quotation marks, and hash symbols are used differently according to the language's syntax rules and may not effectively create a comment in the context of MOV_ step instructions. Therefore, the correct choice aligns with widely accepted commenting practices that aid in better understanding of the code.
