But the whole point of the fairly flexible survex 'enter it like it is
in the book' format/philosophy is to save you that sort of faff and
avoid the conseqent errors. 

Survex already has 'topofil-style' support with fromcount/tocount so you
should just be able to enter the length readings as recorded with
something like

interleaved:

*data diving station depth newline compass count

or for non-interleaved:

* data diving from fromdepth fromcount to todepth tocount compass 

Have you tried that and found problems (in either survex or therion)?
