EXAMPLE:

; Fibonacci sequence
; Computes first 10 Fibonacci numbers
; Results stored at DS:0200h

  MOV CX, 10      ; count
  MOV SI, 0200h   ; output address
  MOV AX, 0       ; fib(0) = 0
  MOV BX, 1       ; fib(1) = 1

fib_loop:
  MOV [SI], AX    ; store current
  ADD SI, 2
  MOV DX, AX
  ADD DX, BX      ; next = current + prev
  MOV AX, BX
  MOV BX, DX
  LOOP fib_loop
