... It does parse and trace,  but nothing appears on the screen.
Messages: 1 frame level object; 1 infinite.   // my plane object !
... I think it is my fault,  cause I just tried,  a minute ago,  with
a simple csg object,  without any kind of randomness and #local,
and it doesn' t work anymore !

in fact,  the following code doesn' t work at all...
#declare YOUR_ARRAY = array[20][20]
#declare i = 0;
#while (i<20)
#declare j=0;
#while (j<20)
#declare YOUR_ARRAY[i][j] = sphere { 0, 1 pigment { White }}
#declare j=j+1;
#end
#declare i=i+1;
#end

Have I to put it into "object {YOUR_ARRAY}", or something like that ?!?
