OK as is normally the case with these things I spotted the error within five minutes of asking for help, but it has raised a another question. My problem was quite simply I had no survey/end survey wrapper. I have been using this index file for over two years and never noticed however it has worked perfectly and produced what I needed.
I now ask why did the index.th compile OK with the other 18 surveys listed in it. The only difference between the first 18 surveys and the last non-working one was that in each scrap of the 18 previous surveys I used the option -station-names "" "@surveyname". I was shown this when I started learning Therion but never really new why. When using this option to make any survey.th compile I have to make sure the map/endmap is outside the survey/endsurvey wrapper. With the my latest survey file I did not use the scrap option and just went with the "normal way" with everything in survey.th within the survey/endsurvey and then the index .th failed due to having no survey/endsurvey wrapper. Clearly I do not yet fully understand the process even though I can make things work, so lots more reading I think. Does anyone know of a good explanation somewhere, most thing I read I find a little confusing. Also if someone would like to explain the -station-names "" "@surveyname" bit I would be very grateful. I suspect I'm not the only one to have struggled with this. Thanks for the previous answers guys.

I do this intentionally while I am drawing up a new piece of passage, then remove the survey map once I am finished.

Everything compiles but the pdf shows the new cave as shots and splays not as the normal walls etc you would expect in a map. All other caves display correctly as intended. Has anyone point out what I am doing wrong. Nick
