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)?
