ABS just means A Basic System, which is the name I've used for the 1d12 version of the game I called ABS12.
This is meant to help emulate a gamemaster when playing alone using the system. A question is asked about the scene, situation, or facts about the current game. It's as if asking the storyteller about what is happening. The appropriate die for the system is then rolled. The chart is consulted and then interpreted.
Does the character see anything around?
Yes, your character sees something.
