it loads the page that the absolute address in ahl is on and make hl
point to the right place. ick, it converts an absolute address in ahl to
a normal address in hl
i think it's in ti86abs.inc

this will copy the entire string to start at _OP1. i would suggest using
somewhere else, though 'cause it might overflow
ld c,(hl)
inc hl
ld b,(hl)
inc hl
ld de,_OP1

if you only need the first byte, you might consider:
(after _load_ram_ahl)
inc hl
inc hl
ld a,(hl)
now a=the first byte of the string

try setting bit 7 at (iy+$12) as well and clear it when you're done.
