Actually, after looking at the code, getting this:
	d pc
	d text

Working shouldn't be that hard.  I just need to add CPU/DSP flag to
Eval_Range() function calls and then user can give range start & end
addresses as also as varibles, registers or symbol values.

For arithmetic expressions ("pc+$20") and indirect addressing ("(a0)"),
one will still need quotes, but I don't those are needed that much.
