Thanks Peter. I obviously didn't remember correctly. It's something I spend a lot of my time trying to avoid.

I've just gone back to the manual and it's GOSUB / RETURN and ON nbr GOTO | GOSUB that are obsolete, not GOTO. I wondered how I was going to manage without that. ;)

This conversation reminds me of this article. Pretty interesting stuff, but the synopsis is that NASA only uses PI to 15 decimal places, because even at that - a 48 billion KM diameter circle (the rough distance to Voyager 1) would have an error of 1 cm.

I'm not sure what to think on this.
The answer for presentation should at least be a float, and arguably with 2 sig fig if scientific notation is to be used.. And the machine should flag any calculation/variable used outside its accuracy limits. It is probably not an issue for most Basic intended use though.
