No,  I am still working with the 3.1 version because my computer does
not accept 800*600 screen minimum requirement...  I plan to solve
this problem soon,  with a more recent computer...

I decided to do what I wanted to do in simulating an array
with two #while loops, and it finally worked.
But if you could see why the famous array
did not work,  here is the code :

#declare s1 = seed(1);
#macro bin_01 ()  // note that it works well with a simple while, without array....
  #local obj_temp =
  #if ( rand(s1) <= 0.5 )
    object { nice_zero }
  #else
    object { nice_one }
  #end
  object { obj_temp }
#end

#declare YOUR_ARRAY = array[20][20]
#declare i = 0;
#while (i<20)
#declare j=0;
#while (j<20)
#declare YOUR_ARRAY[i][j] = bin_01()
#declare j=j+1;
#end
#declare i=i+1;
#end
