Carl:

       Yes, I want the + Vector of my arctan2 which is called Arctan()
in the attached files.  I mainly use this function to find the direction
of travel of a line or the start & stop angles of an arc.

        I use many of your routines and also Colin Taylor's routines.
The best way to explain this was with demo programs & includes.
I apologize for attaching these to anyone not interested in math.

        I use Boolean logic in many of my functions and if you don't understand
Boolean logic, it gets hard to explain.

        I mainly write commercial programs using Euphoria for complicated ACAD
programs requiring extensive math which is not suited for ACAS LISP
programming.
