[Therion] Survex use 0/180° not +90/-90

[cawa sorix]

Hi all,

I had an issue today on data with Vulcain topofil data.
On Vulcain topofil the clino is from 0 to 180° and
0 =  +90
90 = 0
180 = -90

I didn't find anything on survex documentation about that.
Do you have any idea about the right setup for the survex line ?

I have no idea what is the right word for the ??

Example :
units compass grad
units clino grad
data normal from to fromcount tocount compass ?? left right up down
1-0        1-1          6762.0    6799.0  385.00  119.00   0.40   0.30
  1.00   1.00
1-1        1-2          6799.0    6999.0  235.00  106.00   0.40   0.40
  0.90   0.20
