(008000):b2hf:[=]{0232031F} | Your character has been saved.
Half of this number is how far south you are from the top of the map, and theother half of the number is how east you are, from the left edge of the map.
I cannot remember which is which, so what i do is i look at the last line of msglog.txt to find out where i am, and then i go a step south (on the world map) and drink a sip of water so that there will be a new msg and see which number changed.
From there it is a matter of counting. Half of my number is 0232 and the other half is 031F, and maybe i left my things at 02400400, so i will need to go southeast -- either mostly south and a tiny bit east, or mostly east and a tiny bit south. the counting is in hexadecimal so 232, 233, 234, 235, 236, 237, 238, 239, 23A, 23B, 23C, 23D, 23E, 23F, 240 = 14 steps in that direction and 225 steps in the other direction.
Just keep taking sips of water or eating food now and then to check your progress and adjust your course.
