Lander reads sixteen bytes from /lander.state if the disk has one and starts from those: position, velocity, where the station is, fuel, and which screen to be in. A disk without the file is the game as it always was, which is every other flight in the suite. It exists because some states cannot be flown to. A successful dock needs the lander alongside the station and matched, and NINETY SIX pad files failed to get there - not for want of trying, but because climbing spends sideways speed, so a lander cannot rise while matched and arrives slower than orbital every time. Reaching it wants two burns and a phase. The orbit check had already been deleted for the same reason, and the strike check was flown on a nineteen frame window, which is the sort of fixture that ends up measuring the boot time rather than the physics. Binary, because that is what a file is on this machine. A tool to build one from readable text is a small job for another day; until then the tests write the bytes with the fields named, which reads plainly enough. ---- The buffer is a whole block, and that is not caution ---- osFileRead lands a file in Data Memory and a file is stored in blocks of 256, so reading sixteen bytes into sixteen bytes of room writes over whatever follows. It did: the first version put the buffer in front of the view tables, and the program read its state, wiped the numbers every gauge draws from, and left immediately - "finished" and back to the prompt, with nothing on the screen to say why. Four checks, each seen to fail on its own break: a state file places the lander (row 192 and twelve cells of gauge, against thirty one with no file), a matched approach docks and is paid once and not once a frame, it then rides the station a tile under it, and the same approach unmatched is a wreck. The flown strike fixture and its narrow window are gone.
