#include "s2plot.h"
int main(int argc, char *argv[])

COLOUR col = { 1.0, 1.0, 0.0 }; /* Colour */
char text[32]; /* Text */
float sp = 5.0; /* Speed */
s2opend("/?",argc, argv); /* Open the display */

s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
sp = ss2qss(); /* Get spin speed */
sprintf(text,"Speed = %5.2f",sp); /* Prepare the text */
ns2vtext(xyz, right, up, col, text); /* Right some text */
ss2sas(1); /* Start camera rotating */
