Since, as others have already pointed out, addressable Parameter
and Return stacks aren't possible on Forth Chips, would anyone care to
comment on how one *might* write BASIS Forth code to alter those sizes?
I would definitely want to hide John's code behind a word, such as
	2000 CELLS STACK-ADJUST
	    ( or to be perverse )
	-500 CELLS STACK-ADJUST

Is stack adjustment really a portability problem in general, or is it
*just* the way John wants to do it.
