Manny, ilen and olen specify the sizes of the input and output primitives. ilen is the size of the primitive in the tmd. olen is the output size of the prim in the packet area after processing. You should not have to worry about these, except for ilen maybe. It is really only useful if you are writing a tmd reader and encounter a prim that it does not support, Thereby making it easier to skip over. -JiM
