Xavier I have not addressed your question (as I don't know the answer). Your data files compile on my machine as you describe in your message (an error as submitted, but success if the cave names are changed). I noticed that you have a co-ordinate conversion from one cs to another. Interested to know if the conversion is performed correctly for you? I tried to do this some weeks ago with my data (different co-ordinate systems), and although no errors were raised, the co-ordinates were not transformed at all, the maps and grids printed with the input co-ordinate system, and not the requested output co-ord system. In studying the outputs I get with your data I find the same thing is happening. Am I (we?) misunderstanding how to do the co-ordinate conversions, or is something not working?

Is that a normal behavior? It seems to me that a correct typing should allow having the same names for surveys, stations and maps. Xavier
