68k assembly - plus symbol on address registers

Question

While reverse engineering something for fun, I came across the following piece of assembly:

move.b  (a1)+,(a0)+

I understand that the parentheses mean 'value of', but what does the plus symbol stand for? How would I accurately translate this to C?

Answer 1

(a1)+ accesses memory at a1 and increments a1 by the size of the operation. In this case 1. What you have looks like a part of a typical loop that copies memory.
