[Therion] Missing data

I am still dealing with a lot of legacy data from the 1950s and 1960s 
where clinos were not used.

Using Survex this is not a problem, as I just enter the data after a line:

data normal from to compass tape ignoreall

and the program will run.

In Therion, however, the same circumstance gives the error message:

-- not all data for given style

This is a problem as it would require me to enter a series of zeros, 
which does not equate to reality. In some caves, the altitudes are 
constrained by the use of fixed points, at multiple entrances, which 
allows for this data lack. In Therion I am not so sure how this will work.
