But if R13 is being used as a stack pointer and moves with each call
and return that surely means that the amount of stack any one
subroutine can use for local variables is limited to 4K but the stack
as a whole could be much bigger.
Thanks - I was not aware that I had a 4k limit for local variables in a function, so useful!
