Hello! Im new to kOS. have few quetions. 1. Some plans to add return values from subroutines? 2. How to declare global variables and access them? 3. How to get absolete difference of two rotations? for example KOS lock steering stability is bad. SAS works better. But if I turn on SAS kOS cant control ship. I want to fly on SAS until difference between "prograde" and "facing" will not raise too high. When I make math "set diff to prograde - facing. set diff to diff-R(0,0,diff:roll)." I get some vector with 3 dimensions. How to get absolete value, to allow me use command like "until diff > 15 {SAS ON}. SAS OFF.}
