 		 #139589 - want to spare bytes?
Responding to: ???'s previous message

Based on that, I'm actually surprised that nobody has found a way to shave another byte or two out of the line editor program.


Want to spare 2 bytes?

Replace 2 CALLs by ACALLs! :-)

OK that's easy and nasty, as placing it into a bigger program might lead to errors. Some asms know to optimize CALLs into ACALLs if the called routine is BEFORE the call itself.

The EatLoop was cool, you learned something in those classes... :-)

I think we can close this as "Problem Solved" now... Working on the next Weekend Quiz.
