Re: A86: Push/ret
yes.
numbers on the stack are just numbers. how they're interpreted depens
only on how they're removed from the stack.
as long as you keep track of what's on the stack and make sure you've
always got the right code address on the stack when you do a ret, then
everthing will be happy. how it got there is completely unimportant.
