+**  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.
