What is the purpose of the Pause or Step commands during program execution?

• A. To pause execution indefinitely.
• B. To step through code incrementally and observe robot behavior for debugging.
• C. To reset the program to the beginning.
• D. To save the program state to disk.

Answer: (B)

Pause and Step are debugging tools used while a program runs to watch exactly how the robot behaves in small, controllable increments. Step moves the execution forward one instruction or one small block, then stops so you can inspect what changed—like the robot’s pose, joint angles, tool status, I/O signals, and any variables or registers. Pause halts execution at a chosen point, letting you inspect the current state and conditions without the program continuing, then you can resume to see what happens next. This approach helps you verify logic, timing, and safety checks before running the remainder of the program at normal speed. They aren’t meant to reset the program, save state to disk, or keep the robot paused indefinitely without a resume action.
