  I think that we are talking about different things here.

  You can't make a list structure with the povray script language. Arrays
are a bad substitute since you can't change their size after creation.

  I think that 'new' and 'delete' along with pointers may be a good idea
for the next povray version (perhaps pov4?).
  Something like:

#declare MyObject =
  sphere
  { 0,1 pigment { rgb 1 }
    MyObject* next;
  }

#declare ObjectList = null;

#declare Ind=0;
#while(Ind<100)
  #declare Obj = new MyObject;
  #declare Obj.next = ObjectList;
  #declare ObjectList = Obj;
  #declare Ind=Ind+1;
#end

#declare Obj = ObjectList;
#while(Obj != null)
  object { Obj translate x*Ind }
  #declare Obj = Obj.next;
#end


  It shouldn't be very difficult to achieve...
