It won't matter with the current code base. Integer mode doesn't change registers on STO/RCL.

I realized have a need to compare the two register values to see if there's a change, and I'll need to get them onto the stack unmangled anyway in order to do that, so might as well just STO after I'm done comparing.

I should have implemented a R-CMP? to compare blocks of registers Smile
