int main(int argc, char *argv[])
{
s2opend("/?",argc, argv); /* Open the display */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
s2slw(4); /* Set line width */
s2sci(S2_PG_YELLOW);
s2pt1(0.0, 0.0, 0.0, 1); /* Draw a yellow point */
s2sci(S2_PG_RED);
s2pt1(0.3, 0.5, 0.8, 1); /* Draw a red point */
