Explanation of Parameters

N	(I)	The length of array UPX, UPY, UPZ
UPX, UPY, UPZ	(R)	An array of length N. Gives the (X, Y, Z,) coordinates for the points of a polyline in UC.
VPX, VPY, VPZ	(R)	An array of length N. Gives the (X, Y, Z,) coordinates for the points of a polyline in VC.
INDEX	(I)	The line index. See SCSPLI.
