I use move.l 0(a2,d0.l),d2 Note that you can use word or long index registers (word is sign-extended to 32 bits), so you need to specify the size. This is Manx-acceptable syntax. (I wrote a lot of "and.l 4(a4,d4.w),d5" code in a wierd inner loop a while back, so I was glad for the addressing mode's idiosyncracies.) -- -Colin
