Thanks, but I thought perhaps that the three BM? refer to the bonus missions, as in T-Theme, L-lose and W-Win. HYP is perhaps for Hyperspace (Black Hole, Wormhole) NEB is Nebula, ASB is for Asteroid Base?, SRS is maybe Shipping Routes, SPA can be for space, when going outside the mission parameters, DSP is Deep Space or dust cloud?, SMA is that for Small Asteroids? Anybody help....
