What is editing able to perform within the interface?

• A. Editing can modify any part of the job including root instructions.
• B. Editing is only used for adding new steps.
• C. Editing has no effect on numeric data.
• D. Editing can be performed within the Edit Buffer Line; the JOB CONTENT screen remains in view. It can only be used to modify existing numeric data or to change the motion type of an existing step.

Answer: (D)

Editing in this interface is about making targeted changes to what already exists in the job. The Edit Buffer Line is the place you input changes, while the JOB CONTENT screen stays in view so you can see the current sequence as you adjust things. This setup keeps the overall program structure intact, so you can tweak numeric data values or switch the motion type of an existing step without altering root instructions or adding new steps. In short, editing is a focused in-place adjustment of existing data, not a way to rewrite the program or insert new content.
