# SlotToReg moves data into a register from memory.
# RegToSlot moves data into memory from a register.
# Both use a base memory (a register)
# This is because that is what cpu's can do. In programming terms this would be accessing
# an element in an array, in the case of SlotToReg setting the value in the array.
