Notice how the 4th register reading is completely off?

I checked the published code (in the old forum) several times, and cannot find a fault in the way I entered it. Can anyone try it and check if the answer matched the real value, or the one I get? And if the later, how come it was never spotted before?

FTR: I copied the listing from the old forum's post and converted it into a raw file which then was used in V41. In Turbo mode the program finished quickly, and here is the result: Yes, it's the same as yours. R01..03 are fine, then the result is off.
