The codes worked as expected on 32s, 32sii, and 42s. I am however puzzled by the DEG function in the 42s code. I can't think of any reason why the calculator needs to be repeatedly put into degrees mode. Maybe it is a filler instruction to ensure a fair comparison of same numbers of instructions?

Maybe it's a do-nothing instruction needed for the test.
