Thanks Martin, but this does not solve the problem for the reuse of all toporobot surveys: using either data dimension or [] means changing a lot in the data and I want to stay close to the original data so that I can verify the translation errors. What I don't understand is: * why a horizontal shot of 1mm should be considered as vertical for displaying the LRUD? * why vertical shots are always oriented north even though a direction is given?

To specify the LRUD at the beginning of a leg (or when a is a sudden change) it is usual in toporobot to make a null (or very small) length shot (this is also usual in other survey softwares such as vtopo).
example A.
data dimensions station left right up down #you may use this definition of data for all stations just separate LRUD from survey shots.
0 1 2 3 4
data normal compass clino length left right up down
0 1 185 -15 4,5 1 1 5 1
.....
example B:
data normal compass clino length left right up down
0 1 185 -15 4,5 [1 1] [2 1] [3 5] [4 1] #you may use this syntax for LRUD anywhere the LRUD are changed on particular station 1 2 201 10 12 2 3 1 2
....
LRUD in brackets mean first one for LRUD at "from" station, second one for LRUD at "to" station.
