[Therion] How to "equate" between two caves

[Bill Gee]

Hello everyone -
 
I have been working on a multi-cave project for a while.  Each cave exists as 
its own separate set of files.  A few months ago - with help from this group - 
I figured out how to get a single output file that contains all four cave 
maps.
 
The combined map is generated from a single thconfig file that uses "source" 
commands to bring in the .th files from each of the member caves.
 
Now we have surveyed a link between two of the four caves.  I need to set up 
an "equate" command so that the two caves actually link up.  According to 
Aven, the gap is about 30 feet.  Some of that, I am sure, is due to rounding 
errors in the GPS locates for the two caves.  
 
Based on a message from Martin, I added a .th file which contains a "survey" 
command.  However, that is generating an error from Therion:

The thconfig and .th files I used are embedded below as text.
 
Where should I put the "equate" command that will link the two caves?
 
Thanks!
