That is the ^ character, and we use it to separate different fields combined into a single variable. “item” contains 10 separate fields, the first five of which are mandatory: cart-id ^ part number ^ description ^ cost ^ quantity This method avoids having five separate “hidden” variables to convey the same information, saving time and space.
