53 ** MOVE UNDER WARP POWER
55 ** This is both the "move" and the "ram" commands, differing
56 ** only in the flag 'fl'. It is also used for automatic
57 ** emergency override mode, when 'fl' is < 0 and 'c' and 'd'
58 ** are the course and distance to be moved. If 'fl' >= 0,
59 ** the course and distance are asked of the captain.
61 ** The guts of this routine are in the routine move(), which
62 ** is shared with impulse(). Also, the working part of this
63 ** routine is very small; the rest is to handle the slight chance
64 ** that you may be moving at some riduculous speed. In that
65 ** case, there is code to handle time warps, etc.
