or for non-interleaved:

I have tried this (in SURVEX only -  v. 1.1.14) and confirm that it works

To be honest, my method of recording data underwater consists of:

 

distance depth compass newline left right up down

 

since SURVEX requires me to asign station names and put the data into a different layout that the way I wrote it down* some pre-processing of data is acceptable.  Personally I prefer the interleaved format as there are less numbers to type in (or generate if using a spreadsheet to tranform my way into that required by the SURVEX engine).

* you've got to understand that there's a certain amount of task loading involved in conducting an underwater cave survey, it's a bonus if I can actually see what I'm writing down or read my instruments - hence the SONAR wand is handy in passages 7 m across in 1 m visibility.
