LXPNTS(npnts.i2.r, ixydat.i2.r [,kolor.i1.r])
This routine will plot NPNTS points on the LX color graphics display
window with color code KOLOR. IXYDAT is an integer array which
contains the coordinates of the points as follows: IX1, IY1, IX2,
IY2, ...., IXn, IYn. Valid X-coordinates are in the range [0,639]
and valid Y-coordinates are in the range [0,511]. (0,0) is in the
lower left corner of the display. See the descriptions of the LXPNT
and the LXMODE routines for information on the use of color codes.
