I have been coding for the P2 and I find in particular SETR seems wrong.
We have ALTR which means substitute the "R"esult address and ALTI which means substitute the "I"nstruction. Hence SETI or MOVI seems a better fit.
We have MOVBYTS, and so MOVI/MOVD/MOVS seems a better fit. There is also the benefit that the P1 uses MOVI/MOVD/MOVS.
And yes, we do have SET/GET/ROL triplets for BYTE and WORD. We don't have pairs/triplets for MOVI/MOVD/MOVS. May have been nice for I & D but not a great case for usage.
BTW this is only a compiler change, not a silicon change.
