OK, good to know. Which brings me to another question: Can I use decimal
gps positions (like the ones Google use) to pinpoint stations? I tried the
following, but I don't know if that's correct:
*cs out s-merc
*fix A 59.9100129 10.6824754 0

So it parses the comments as well?
And don't you know it, another question: The depth bar on the top-right
side in Aven seems wrong with my test data:
*data diving from to length bearing fromdepth todepth
A B 25 160 12 16
B C 12 120 16 20
The depth bar goes from 4m to 8m. How do I make it go from 12 to 20?
Thanks for all your help!
