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