OFF TOPIC! General Registers

[MikeB]

I am reviewing some assembly notes, simply out of curiosity, and I come across something that I am not sure of. In the 8088 processor, you can access the general registers high byte and low byte by denoting with a H or L respectively. In DEBUG, I typed the following:

- R AH

and it gives me an error. Can I not access the high and low byte of the general registers on a P4 processor?
