Which of the following statements about the INFORM LIST is true?

• A. It lists all motion commands
• B. It lists all non-motion commands
• C. It lists all error messages
• D. It lists only memory addresses

Answer: (B)

An INFORM LIST is a reference of commands that do not move the robot. It groups the non-motion tasks you use in programming, such as reading inputs, manipulating variables, branching, subroutine calls, and querying system status. That focus on non-movement actions is why this list is the place to look for non-motion commands, rather than movement commands or other items. The option stating it lists all non-motion commands fits because motion commands are handled separately, error messages are not commands, and memory addresses are about data location, not a catalog of commands. If you’re implementing logic or IO operations, the INFORM LIST is where you’ll find the relevant commands.
