37 ** call starbase for help
39 ** First, the closest starbase is selected. If there is a
40 ** a starbase in your own quadrant, you are in good shape.
41 ** This distance takes quadrant distances into account only.
43 ** A magic number is computed based on the distance which acts
44 ** as the probability that you will be rematerialized. You
47 ** When it is determined that you should be able to be remater-
48 ** ialized (i.e., when the probability thing mentioned above
49 ** comes up positive), you are put into that quadrant (anywhere).
50 ** Then, we try to see if there is a spot adjacent to the star-
51 ** base. If not, you can't be rematerialized!!! Otherwise,
52 ** it drops you there. It only tries five times to find a spot
53 ** to drop you. After that, it's your problem.
