OK, by "register" I mean strictly something which is software-visible - like "$2" or the coprocessor-zero register called "EPC". There is no PC register in my sense, and if you've found a manual claiming that one exists, that manual is wrong - send me URL and tell me how to find this text. -- Dominic
