Ah, perhaps a poor choice of words. I should really have said it has been suggested in conversations I've heard in the past that because nothing(!) uses any value other than zero in that field, they could reclaim a big chunk of number space for new instructions/encodings. Whether or not any of this was suggested as something ARM are actually planning to do is beyond my recollection because the relevant conversations were years ago. In summary: I really mean that we shouldn't be surprised to see a future generation of the ARM architecture that does this and gives RISC OS a massive problem. Just like the way that we should be surprised in the future if ARM drop the ARM instruction set all together and move over to Thumb2 or something... :-| Ta, Steve -- Steve Revill @ Home Note: All opinions expressed herein are my own.
