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