42 | ** SHIELD AND CLOAKING DEVICE CONTROL | |
43 | ** | |
44 | ** 'f' is one for auto shield up (in case of Condition RED), | |
45 | ** zero for shield control, and negative one for cloaking | |
46 | ** device control. | |
47 | ** | |
48 | ** Called with an 'up' or 'down' on the same line, it puts | |
49 | ** the shields/cloak into the specified mode. Otherwise it | |
50 | ** reports to the user the current mode, and asks if she wishes | |
51 | ** to change. | |
52 | ** | |
53 | ** This is not a free move. Hits that occur as a result of | |
54 | ** this move appear as though the shields are half up/down, | |
55 | ** so you get partial hits. | |
