The semi-automatic program P66 was used to move the lunar module over the lunar surface.
The AGC was controlling the thrust of the main engine so to maintain the lunar module over the lunar surface, while the crew was using the RCS to move the lunar module in the desired direction.
The AGC also had to take into accound orders from the crew to move the lunar module up and down, so that they could choose at what altitude the lunar module had to move.
In a previous video, we have already seen that the AGC had no way to send a thrust control command to the LGC, which means that there already is a problem with this program, for the AGC could not send what it has calculated to the LGC.
In fact, I show that the AGC does not even correctly calculate the necessary thrust in this program, and, still worse (or better), what it does in this program is outright aberrant.
