I agree. I've moved the handling of the PC (do_rtn) up in order to get it out of XROM space for subsequent calls to lift() or lower(). I've made a short test with IDIV and it seems to be working now. Some more testing might be required. Solve, integrate, sum and product aren't affected at all because they don't use the xIN/xOUT mechanics but other XROM based commands are.
