| 9 | ** SHIELD AND CLOAKING DEVICE CONTROL |
| 10 | ** |
| 11 | ** 'f' is one for auto shield up (in case of Condition RED), |
| 12 | ** zero for shield control, and negative one for cloaking |
| 13 | ** device control. |
| 14 | ** |
| 15 | ** Called with an 'up' or 'down' on the same line, it puts |
| 16 | ** the shields/cloak into the specified mode. Otherwise it |
| 17 | ** reports to the user the current mode, and asks if she wishes |
| 18 | ** to change. |
| 19 | ** |
| 20 | ** This is not a free move. Hits that occur as a result of |
| 21 | ** this move appear as though the shields are half up/down, |
| 22 | ** so you get partial hits. |
