Exactly, because the value in X is the one that's otherwise going to get clobbered by the operation, so this is the only way of bringing it back from the dead.

I see where you're coming from, but the whole point of register arithmetic operations is that they mean you don't recall anything into the stack, thus preserving T as a positive side effect. In this respect, "RCL[op] nn" and "RCL nn [op]" are not functionally equivalent at all.

There are only 10 types of people in this world. Those who understand binary and those who don't.
