Line 83:
Here, the offset is performed ''before'' the storage operation. What if you want to offset afterwards? That would be useful for reading in a data stream. Good news - you can do that simply by having the offset value or register '''outside''' the brackets. This is called "post-increment" or "post-indexing." Unlike pre-indexing, these changes to the pointer are not temporary.
