Naming Arrays

Hi,
  Is there any way by which some sort of special attribute can be
assigned to instructions. like for e.g. is it possible to assign a name to
array created using InstructionFactory.createNewArray(). The problem that
I am facing is because of not being able to distinguish between
instructions of original class file from that of instructions being added
to that class file using BCEL.

I want to perform some action on array instructions. Before doing that I
I am also adding some array instructions to the class file in some
other step.

So when I perform modification of array instructions, the array
instructions added in the first step also get modified. Previously I
distinguished between such instructions by adding NOPs before modified
instruction. However, I was wondering whethere this can be done more
elegantly.

Hope I have made my point clear.

Thanks and Regards
