How can I find a vector (any vector) that is perpendicular to another vector
(that I already have)?
I need something I can use in an algorithm for solving this.

Thank you for any info.

Look at description of vcross vector function in your POV manual. Ask for
details if it is not enough for you.

VPerp_To_Vector(v0) in math.inc. Or if you have two vectors, 
VPerp_To_Plane(V1, V2).
