from a list:
load var name to op1
call findsym
ld a,b
(you should store ade someplace if you use this var a lot so you can skip
findsym later)
load index to hl
call _GETLTOOP1 (use _PUTTOL to store op1 to that index)

from a matrix:
get address of matrix in ade (as above)
load row,col to b,c
call _GETMTOOP1 (_PUTTOMA1 to store)

_ADRMROW & _ADRMELE can be used if you just want the address in a matrix
(eg, if you're gonna read&write the same item)
_ADRLELE for address in list
