       Name: FAROF2                                                  [Show more]
       Type: Subroutine
   Category: Maths (Geometry)
    Summary: Compare x_hi, y_hi and z_hi with A
    Context: See this subroutine in context in the source code
 References: This subroutine is called as follows:
             * Main flight loop (Part 14 of 16) calls FAROF2


 Compare x_hi, y_hi and z_hi with A, and set the C flag if all three <= A,
 otherwise clear the C flag.


 Returns:

   C flag               Set if x_hi <= A and y_hi <= A and z_hi <= A

                        Clear otherwise (i.e. if any one of them are bigger than
                        A)
