My aging Nikon DTM-730 has onboard DC capabilities and can export field data
in "TDS" format. The test example below is from a 3-station, closed loop
traverse (measured in the office's parking lot). On the first setup
(station 10), I told the Nikon that my backsight was station 99 and
assigned it a back azimuth of 65°. The final setup was on station 12 where
I turned an angle back to station 10 (assigning 10 the foresight point
number 13). When I export from Nikon format into TDS (using the Nikon's
onboard DC software), this is the ascii file that I end up with:

I designated every reading as a "sideshot" in the Nikon DC software (even
the control). When I import the above file into Carlson's "Raw Editor", it
seems to choke on the records that start with "OC".
If I strip the "OC" records out of the file (and the comments to improve
readability), I end up with this:

.. . . which imports nicely into Carlson's "Raw Editor". The traverse legs
and sideshots are drawn and I can process the data to adjust for misclosure.
Three questions:
1) Is the TDS file that my old Nikon gun creates using a an up-to-date "TDS"
format that Carslon understands?
2) What are the "OC" records? I googled for a specification on the "TDS"
file format but didn't find anything. I am assuming that the Nikon creates
the "OC" record during the "station setup" procedure required when the
instrument is powered on and told what point it is setup over.
3) Or, should I get used to editting these raw files before importing?
Btw ... Here's what the Nikon-format raw file looks like (as exported from
the the gun's DC software onto the datacard):
