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.
