I decided not to include it at the last second because when I tried it, it
didn't work, so I said screw it.  Pat added those two to ti86asm.inc
recently, though

_runindicoff                     equ            4AB1h
_runindicon                      equ            4AADh

those should be self-explanatory

don't know, never needed to do it

there's probably a call to clear the graph screen, but here's the code

	ld hl,$C9FA	;address of graph screen
	ld de,$C9FB
	ld bc,$03FF
	ld (hl),0
	ldir		;now it's all clear

I don't know about that last question
