Sorry, here is the complete listing:

//exemple de param3d
t=0:0.1:5*%pi;
npt = size(t,"*");
param3d(sin(t(1:2)),cos(t(1:2)),t(1:2)/10,35,45,"X at Y@Z");

he=gce(); //the handle on the 3D polyline
he.foreground=color('red');

ha=gca(); //the handle on the axes
ha.rotation_angles=[60 80];
ha.data_bounds = [-1,-1,0;1,1,5];

for j = 1:npt
     drawlater();
     he.children(1).data = [sin(t(1:j));cos(t(1:j)); t(1:j)]';
     drawnow();
end;

and here is the error message

  !--error 246
