As I said in my first email, I have used that, however, the thbook also states that
entrance 0
Should work in survey, to define a cave in the cave-list assumably for multi entrance systems then
station 0 "" entrance
can be used for other entrances.
The original email I sent gave your solution, but the thbook command as stated in my original email does not work.

"not enough data readings" - because it´s written under command data normal from to ... Proper way to use it is following:

survey -title "Cave name"

centerline
station 0 "Cave name" entrance
...
data normal from to compass clino ...
...
endcenterline
ensurvey

Then things works well.

The Therion book states it has to be in survey, I tried
entrance 0
in centreline, then you get an error, not enough data readings.

Yes I know what it is meant to do, but it is not working, I will post
examples when I am back in the UK, not easily done from rural
Myanmar....

Definition of entrance has to be inside centerline.
Then "export cave-list -location on -o cave.html" gives you
coordinates and lenght and depth of your surveys compiled, conected
with defined entrances. If you have a index.th [1], which connects
all your caves (every cave has to be at least in one or more
surveys; and more surveys connected under one general cave survey),
then you have list of all caves with one or more defined entrances.

Yes, that is what I said, and it gives an error

Page 17 of the Therion hook states that station <station name>
Under the context survey should be used as the entrance identifier
for a cave to be used in cave-list export.

However, this gives an error unknown command -- entrance

Now I can sort of get round it using
Station 0 "" entrance
in the centerline, but this does not define a cave so the list is
a bit weird. Am I missing something?
