Great. But for a complete solution you'd have to add a FIX 0, and this makes it one of the possible 3 step solutions. But on an HP67 it's even 4 steps, or 4 bytes on the '41.

However, logs usually are a bit slow, and changing the display mode should be avoided, if possible. But it can be done with the same 3 steps without logs and without a special display setting.
