the contents of the B Register or X register (pointer register). The pointer register is automatically incremented or

decremented after execution, allowing easy manipulation of memory blocks with software loops. In assembly

language, the notation [B+], [B−], [X+], or [X−] specifies which register serves as the pointer, and whether the

pointer is to be incremented or decremented.
