In your example, you got it right. If the target course is X, your course would be X+90 coming from starboard, or X-90 coming coming from port. If the X+- values are < 360 add 360, if >360 subtract 360.
What I meant to say is: If values are < 0, add 360, and if > 360, subtract 360. Sorry for the confusion.
