2.6.2 SGPLU/SGPLV/SGPLR

1.

Function

Draws a polyline in the U/V/R-coordinates.

2.

Call

CALL SGPLU(N,UPX,UPY)
CALL SGPLV(N,VPX,VPY)
CALL SGPLR(N,RPX,RPY)

3.

Explanation of Parameters

N	(I)	Length of array UPX, UPY.
UPX, UPY	(R)	An array with length N. Gives the (X, Y) coordinates of points to connect to form the polyline in the UC.
VPX, VPY	(R)	An array with length N. Gives the (X, Y) coordinates of points to connect to form the polyline in the VC.
RPX, RPY	(R)	An array with length N. Gives the (X, Y) coordinates of points to connect to form the polyline in the RC.

Notes

(a)

N must be larger than 2.

(b)

The attribute of the polyline is set by SGSPLT and SGSPLI.
