This is part of the main game loop. This is where the core loop of the game lives, and it's in two parts. The shorter loop (just parts 5 and 6) is iterated when we are docked, while the entire loop from part 1 to 6 iterates if we are in space. This section covers the following: * Spawn a trader, i.e. a Cobra Mk III that isn't hostile, with one missile, a 50% chance of having an E.C.M., a speed between 16 and 31, and a gentle clockwise roll We call this from within the main loop, with A set to a random number and the C flag set.
