I've already suggested that locals are a Good Thing as the compiler can overlay them.

I'd previously thought that keeping locals in the innermost scope possible would get a further benefit from overlaying - but someone on the Keil forum recently suggested that this is not so.

Can you comment?

(thinking about it, it looks like the Keil Linkers do overlaying on a function-by-function basis - so using inner scope within a function wouldn't help...?)
