     51 **	randomly, except for the starship, which goes into a fixed
     52 **	sector.
     53 **
     54 **	If there are Klingons in the quadrant, the captain is informed
     55 **	that the condition is RED, and he is given a chance to put
     56 **	his shields up if the computer is working.
     57 **
     58 **	The flag `f' is set to disable the check for condition red.
     59 **	This mode is used in situations where you know you are going
     60 **	to be docked, i.e., abandon() and help().
