The SOUTH command
Typing SOUTH means GO SOUTH or WALK SOUTH. That is, direct the player character southward from their current location. Assuming there's an exit in that direction and nothing is blocking or hindering the character, the PC will travel south to an adjacent location.

Directions like SOUTH tend to be implemented both as room properties and as objects in their own right. The SOUTH command, however, tends to be parsed or reinterpreted as a GO command acting on the south object.
