Yes, and this program looks like it was unrolled to the point where there's literally no loop left! It's a bit hard to read but it looks like the same five lines repeated over and over?

That was my immediate assessment of it too. It's basically the same 5 steps repeated for almost 220 steps, plus a LBL B to calculate the results. I found the "Will take 43 sets (ft)(oz) no more" note rather humorous, considering you could rewrite the whole program in about 20 steps and eliminate that limitation at the same time.
