Rumor has it that Ron Hudson may have mentioned these words:

Sure... I've seen examples (and made one, *years* ago) in Microsoft Basic
on my CoCo.

If you consider MERGEing different basic programs (if you MERGE in a new
program where line numbers match, most basics that I'd worked with would
replace the original statement with the new... if you count that, it was
rather common in the CoCo world.

I'd seen one in applesoft basic as well -- it had to do with
self-populating DATA statements, IIRC.
