In what way does BAKR...PR not let you accomplish that (if by "state" you are referring to thing such as registers and PSW state)? BAKR 14,0 ... PR with this sometimes being preceded by BSM 14,0 in order to make sure that the reg 14 is properly defined for the AMODE needed (unnecessary if you got here by something like BASR 14,15 or BRASL 14,xxx). As pointed out, this would still be considerably slower than the analogous register saving/restoring.
